I am making use of non-static import
JsonPath jp = response.jsonPath();
System.out.println(jp.get("data?(#.id>14).employee_name").toString());
For a JSON as shown below:
{"status":"success","data":[{"id":"1","employee_name":"Tiger Nixon","employee_salary":"320800","employee_age":"61","profile_image":""},{"id":"2","employee_name":"Garrett Winters","employee_salary":"170750","employee_age":"63","profile_image":""}]}
When i am trying to run it , i am getting below error:
java.lang.IllegalArgumentException: Invalid JSON expression:
Script1.groovy: 1: expecting EOF, found '[' # line 1, column 31.
data[?(#.id>14)].employee_name
^
1 error
Can someone guide me why is this error being thrown ?
I doubt if that syntax is right, nonetheless, you should be using the below
Also note that the id is a string in your response so you will have to include it in quotes
js.get("data.find {it.id > '14'}.employee_name").toString();
I am doing test driven development in Julia.
The test expects a certain exception to be thrown.
How do I throw the expected exception?
I'm looping through a string and counting the occurrence of specific letters.
Any letter than 'A','C','G',or'T' should result in an exception
Running Julia version 1.2.0.
I have tried these alternatives:
throw(DomainError())
throw(DomainError)
throw("DomainError")
I expected those to work based on this resource:
https://scls.gitbooks.io/ljthw/content/_chapters/11-ex8.html
Here is a link to the problem I am trying to solve:
https://exercism.io/my/solutions/781af1c1f9e2448cac57c0707aced90f
(Heads up: That link may be unique to my login)
My code:
function count_nucleotides(strand::AbstractString)
Counts = Dict()
Counts['A'] = 0
Counts['C'] = 0
Counts['G'] = 0
Counts['T'] = 0
for ch in strand
# println(ch)
if ch=='A'
Counts['A'] += 1
# Counts['A'] = Counts['A'] + 1
elseif ch=='C'
Counts['C'] += 1
elseif ch=='G'
Counts['G'] += 1
elseif ch=='T'
Counts['T'] += 1
else
throw(DomainError())
end
end
return Counts
end
The test:
#testset "strand with invalid nucleotides" begin
#test_throws DomainError count_nucleotides("AGXXACT")
end
My error report, see the lines with: Expected and Thrown.

ERROR: LoadError: Some tests did not pass: 0 passed, 1 failed, 0 errored, 0 broken.
The MethodError comes from the call to DomainError -- there are no zero-argument constructor for this exception type. From the docs:
help?> DomainError
DomainError(val)
DomainError(val, msg)
The argument val to a function or constructor is outside the valid domain.
So there are one constructor which takes the value that was out of the domain, and one that, in addition, takes an extra message string. You could e.g. do
throw(DomainError(ch))
or
throw(DomainError(ch, "this character is bad"))
I've been trying to pattern for the case where a user types in an invalid directory:
# let dir = Unix.opendir "adfalf";;
Exception: Unix.Unix_error (Unix.ENOENT, "opendir", "adfalf").
My function is as follows:
let files_of_dir d =
try
let dir = Unix.opendir d in
...
with
Unix_error (uerr, ucommand, dir) -> raise Not_found
Except I keep getting the compilation error:
Error: This variant pattern is expected to have type exn
The constructor Unix_error does not belong to type exn
I don't understand what I'm doing wrong w/ the pattern matching. If anyone could help me on this it would be greatly appreciated!
Some Other Notes:
I've been compiling my code using the following command on terminal:
ocamlbuild filename.byte
You need to say Unix.Unix_error, not just Unix_error. Note that this is what appears in your sample session.
I can't seem to catch an exception when using json.loads even though I specifically call it out. I largely see this when trying to stress my server with lots of client connection sending data very quickly. See my error below:
(I've replaced my IP address with X's in the error code)
EX: Unterminated string starting at: line 1 column 49 (char 48) Data:
'{"ap-hdop":0.55,"rtcmin":"38","ap-latdec":3.134,"a' error: uncaptured
python exception, closing channel
(:Unterminated string
starting at: line 1 column 49 (char 48)
[//faraday_server_handler.py|collect_incoming_data|34]
[/usr/lib/python2.7/json/init.py|loads|338]
[/usr/lib/python2.7/json/decoder.py|decode|366]
[/usr/lib/python2.7/json/decoder.py|raw_decode|382])
I understand this that the code fails because I simply miss a double quotes on the line:
'{"ap-hdop":0.55,"rtcmin":"38","ap-latdec":3.134,"a'
This line is usually a LOT longer so that "a.... was supposed to keep going and complete it's quotes.
Here's my relevant code:
def collect_incoming_data(self, data):
"""Read an incoming message from the client, place JSON message data into buffer"""
#self.logger.debug('collect_fing_data() -> (%d bytes)\n"""%s"""', len(data), data)
try:
loaded_data = json.loads(data)
except ValueError, ex:
self.handle_error()
type,value,traceback = sys.exc_info()
print type
#print "Collect Incoming Data: " . time.strftime("%Y-%m-%d %H:%M:%S",time.gmtime())
print "EX: ", ex
print "Data: ",repr(data)
Any ideas? I scoured the internet to see if I can find this issue, but I appear to be setting up to capture the exception which everyone else having this issue with loads seems to suggest to do.
EDIT 3/1/2016 - Evening
Commenting out my exception handle_error() let me see more of the error:
except ValueError, ex:
self.handle_error()
type,value,traceback = sys.exc_info()
print type
#print "Collect Incoming Data: " . time.strftime("%Y-%m-%d %H:%M:%S",time.gmtime())
print "EX: ", ex
print "Data: ",repr(data)
Below is my new error, I've commented out personal data. It's apparent that the issue I really have now is in-fact the unterminated string
EX: Unterminated string starting at:

OK my original question was answered which was "Why am I not catching the ValueError exception even though I am providing code to do just that?"
#tadhg McDonald-jensen was correct with his comment to remove my call to handle_error().
I still have some other issues but they are a different question. Thanks!
I am running:
select *
from table
and I am getting this error:
Failed with exception java.io.IOException:org.apache.hadoop.hive.serde2.SerDeException: org.codehaus.jackson.JsonParseException: Unexpected character ('O' (code 79)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')

The tweets are also in a language that I don't know. Is this necessary to have an extension of json in tweets?
You need to change the configuration file in flume. I too faced the issue and resolved by adding the below properties in twitter.conf.
TwitterAgent.sources.Twitter.maxBatchSize = 50000
TwitterAgent.sources.Twitter.maxBatchDurationMillis = 100000
