Steve Varnau commented on TRAFODION-2697:
-----------------------------------------
Since trafodion writes the data and then passes it to hbase, bulkload directory
needs to be write-able by trafodion user and read-able by hbase user, but for
security sake, not read-able by other hdfs users (other). So, we set
permissions 755 on /user/trafodion, 750 on /user/trafodion/bulkload, but set
group on bulkload to hbase's group.
trafodion user should already be part of the hbase group.
We query the group name via the "hdfs groups hbase" command.
> installers should secure bulkload hdfs dir for hbase upload

> both installers should make hdfs:/user/trafodion/bulkload directory so that
> it is readable by hbase user, without making it world-readable.
> This is needed to create hbase index, etc.
