Hi Stack and Nick, Thanks for the reply. @Stack: I went through the following link http://hbase.apache.org/book.html#hbase.tmp.dir before posting my query. hbase.tmp.dir
Temporary directory on the local filesystem. Change this setting to point to a location more permanent than '/tmp' (The '/tmp' directory is often cleared on machine restart). Default: /tmp/hbase-${user.name} IMHO, the description didn't say about the significance/roll of this property. Yes, it would be nice if we can add some more details about this property. @Nick: I am using HBase 0.92.1, CompactionTool.java is part of HBase 0.96 as per https://issues.apache.org/jira/browse/HBASE-7253. I have 10 disks on my slave node that will primarily be used for serving HBase queries(very less MR ). So, i was trying to distribute my disk I/O load evenly among the disk. Will it be fine if i just dedicate 1 disk for hadoop.tmp.dir or 1 disk is also a overkill for hbase.tmp.dir.
