[jira] [Commented] (KYLIN-1422) fuzzy key filter issue on early hbase 1.0.0 versions

["hongbin ma (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KYLIN-1422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15182521#comment-15182521 ] 

hongbin ma commented on KYLIN-1422:
-----------------------------------

the issue is now fixed on a patched version name "1.x-HBase1.1.3" on top of 1.x-staging branch. The branch is for those who deployed hbase higher than 1.1.1,1.0.2,0.98.13 and lower than  1.1.3,1.0.3,0.98.15
(after https://issues.apache.org/jira/browse/HBASE-13761 and before https://issues.apache.org/jira/browse/HBASE-14269)

Users may need to put lib/kylin-coprocessor-${version}.jar  into hbase.dynamic.jars.dir. Do this with caution because:

 <property>
    <name>hbase.dynamic.jars.dir</name>
    <value>${hbase.rootdir}/lib</value>
    <description>
      The directory from which the custom filter/co-processor jars can be loaded
      dynamically by the region server without the need to restart. However,
      an already loaded filter/co-processor class would not be un-loaded. See
      HBASE-1936 for more details.
