I am using MAC Osx for Hadoop Stack and using MySQL as the database for it.I am trying to execute a Sqoop import command:
sqoop import --connect jdbc:mysql://127.0.0.1/emp --table employee --username root --password reality --m 1 --target-dir /sqoop_import
But I am facing below-mentioned issue while executing it. Even in /etc/hosts, localhost is at 127.0.0.1.host file screenshot. I have tried pinging localhost and it works but the error of host is down, still prevails. Please help.

I see that you are having network issues. From the log above it says that local host translates to Mohits-MacBook-Pro.local/192.168.0.103 in you unix system and destination which it is trying to connect is "192.168.0.105":38183. Please go to unix system and see /etc/hosts file and make sure you change localhost to 127.0.0.1.

I am trying to export a hive table to mysql database whose data is tab delimited as stored in HDFS but the job is failing every time after mapper phase.
I have referred to many link and resources and cross checked my export command like export-directory, table name and other factors. Also the schema of both the tables are same but still didn't have any idea why the jobs are failing every time.
Schema in hive :
display_id int
employment_type string
edu_qualification string
marital_status string
job_type string
working_hours_per_week int
country string
salary string
Schema in Mysql
display_id int
employment_type varchar(100)
edu_qualification varchar(100)
marital_status varchar(100)
job_type varchar(100)
working_hours_per_week int
country varchar(100)
salary varchar(100)
Command used for exporting table
sqoop export \
--connect <<jdbcURL>> \
--username root \
--password **** \
--table census_table \
--export-dir <<hdfs_dir>> \
--input-fields-terminated-by '\t' \
--columns "display_id,employment_type,edu_qualification,marital_status,job_type,working_hours_per_week,country,salary" \
--num-mappers 1
Sample data in file
39 StateGov BachelorDegree Unmarried Clerical 45 US <=55K

I have tried almost all possible combinations for export commmand but it didn't get the job done and now i have no idea how to proceed and what i'm doinng wrong. please help or suggest the changes.
NOTE : i'm able to import table from mysql indicating that username, password and jdbcURL that i'm using for --connnect parameters are also verified and working.
Thanks
It can be failing for many reasons, please follow this link to track the log to see why the process is failing

then you could see something like this
clik in logs and you should be able to see
and you could explore why the process is failing.

but i am not sure why this error is coming . when database is present.
MYSQL needs to be installed on all nodes
when we run the mysql command in distributed platform then sqoop expects mysql command should be interpreted on all nodes and thats the reason why we need to install it on all nodes. hope this explains the answer
Am trying to run the below command in cloudera and getting link failure error. I have tried to restart mysqld service too, no use. Kindly some one help friends.
