Subject [jira] [Commented] (PHOENIX-5268) HBase 2.0.5 compatibility
Date Wed, 08 May 2019 06:50:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-5268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16835365#comment-16835365

jaanai commented on PHOENIX-5268:
---------------------------------

{quote}KeyValue is a class marked as Private so by contract is not supposed to be extended
and we can break you at any time. Use Cell, which is a supported Public interface.
{quote}
[~apurtell] IndexedKeyValue is used on the server side, I think we should implement ExtendedCell
for the server side Cell, but ExtendedCell also is a Private class. I try to implement a IndexedKeyValue
class using Cell interface, but some operations can't be supported on the server side. 
{code:java}
java.lang.UnsupportedOperationException: Cell is not of type org.apache.hadoop.hbase.ExtendedCell
	at org.apache.hadoop.hbase.PrivateCellUtil.setSequenceId(PrivateCellUtil.java:2275)
	at org.apache.hadoop.hbase.regionserver.wal.FSWALEntry.stampRegionSequenceId(FSWALEntry.java:118)
	at org.apache.hadoop.hbase.regionserver.wal.AbstractFSWAL.stampSequenceIdAndPublishToRingBuffer(AbstractFSWAL.java:971)
