Subject [jira] [Commented] (HBASE-17648) HBase Table-level synchronization fails between two secured(kerberized) cluster
Date Tue, 14 Feb 2017 18:09:42 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15866289#comment-15866289
] 

Yi Liang commented on HBASE-17648:
----------------------------------

[~tedyu@apache.org], thanks for reviewing,
yes, test this command on a Kerberos as well as a non-Kerberos environment. The 'org.apache.hadoop.hbase.mapreduce.SyncTable'
is successfull and the 'target' table is successfully synced with the 'source' table
