James Taylor commented on PHOENIX-2477:
---------------------------------------

Looks harmless enough (and definitely better than data loss :-) ). Any opinions, [~jesse_yates]?

> 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.
