[jira] [Commented] (PHOENIX-2477) ClassCastException in
IndexedWALEditCodec after HBASE-14501 (possible dataloss)
[ https://issues.apache.org/jira/browse/PHOENIX-2477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15035098#comment-15035098 ]
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.
