why is hbase creating this mapred directory on hdfs??

["Hiller, Dean (Contractor)" <de...@broadridge.com>]

On hdfs, I see this directory being created

 

/deanhdfs/data/hadooptmp/mapred/system

 

ONLY when I start hbase on a brand new hadoop system with no files.

 

On my datanodes, mapred had correctly created

/deanhdfs/data/hadooptmp/mapred/local/

 

And I have even debugged jobs using IsolationRunner out of those local
datanode directories.

 

The ONLY place I refer to /deanhdfs/data/hadooptmp is in "core-site.xml
file" which has just two properties

 

<property>

  <name>fs.default.name</name>

  <value>hdfs://DNVR-DEV3.test.jsq.bsg.ad.adp.com:54310</value>

</property>

<property>

  <name>hadoop.tmp.dir</name>

  <value>/deanhdfs/data/hadooptmp</value>

</property>

 

Any ideas?

Thanks,

Dean
