How come?</P> Sat, 21 May 2016 02:43:21 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Why-is-hbase-hstore-compaction-ratio-missing-from-sandbox/m-p/159781#M29105 sunile_manjee 2016-05-21T02:43:21Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Why-is-hbase-hstore-compaction-ratio-missing-from-sandbox/m-p/159782#M29106 <P>I checked two in-house clusters.</P><P>hbase.hstore.compaction.ratio wasn't in hbase-site.xml there either.

You can play with enabling off peak compaction (when this ratio is set to 5 by default, as far as I remember) as well - hbase.hstore.compaction.ratio.offpeak. </P> Sat, 21 May 2016 04:03:01 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Why-is-hbase-hstore-compaction-ratio-missing-from-sandbox/m-p/159784#M29108 vrodionov 2016-05-21T04:03:01Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Why-is-hbase-hstore-compaction-ratio-missing-from-sandbox/m-p/159785#M29109 <P style="margin-left: 40px;"> <A rel="user" href="https://community.cloudera.com/users/532/tyu.html" nodeid="532">@Ted Yu</A> My mind drew a black about defaults. HBase will use default value unless you specifcy in ambari custom hbase site. thanks</P> Sat, 21 May 2016 04:03:49 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Why-is-hbase-hstore-compaction-ratio-missing-from-sandbox/m-p/159785#M29109 sunile_manjee 2016-05-21T04:03:49Z
