James Taylor commented on PHOENIX-2477:
---------------------------------------
Thanks for checking in your fix, [~enis]. It's ok to check in to only the 4.x
and master branches as these are the only active ones currently.
So given your HBase fix, is there a b/w compat issue in Phoenix? Are we ok,
because there hasn't been an HBase release with the change that would have
broken Phoenix?
> ClassCastException in IndexedWALEditCodec after HBASE-14501 (possible

> HBASE-14501 fixed the semantics in using the InputStream.available() and the
> interface between the actual Decoder and BaseDecoder.
> Running Phoenix with IndexedWALEditCodec on top of an HBase version
> containing HBASE-14501 now causes silent data loss since the Decoder throws
> {code}
> java.lang.ClassCastException: org.apache.hadoop.hbase.codec.BaseDecoder$PBIS
> cannot be cast to java.io.DataInput
> {code}
> which gets silently ignored from ProtobufLogReader.
