Description

When hive query start up a Distcp job as a MapReduce job，it was named as ”distcp:[clipped SQL context]“  by default，when the sql is [insert into mydb.newtb select * from mydb.oldtb], it's like "distcp:insert into mydb.tb...db.oldtb". And this name will be used in lancher.container.sh as the value of TIMELINE_FLOW_NAME_TAG

 

When I use backquote on one of database name and table name,it will cause a bash problem.Like 

export TIMELINE_FLOW_NAME_TAG="distcp: INSERT INTO mydb.ne ...db`.`oldtb` (Stage-1)"

in shell script file.The error is

[container route]/launch_container.sh: line 33: unexpected EOF while looking for matching ``'

 

I can solve this by set mapreduce.job.name to a static name ,just avoid this problem. Perhaps the default naming convention for Distcp tasks can be changed，which SQL context is not included.
