[jira] [Commented] (PHOENIX-2887) Uberjar application fail with
"IllegalAccessError: class com.google.protobuf.ZeroCopyLiteralByteString
cannot access its superclass com.google.protobuf.LiteralByteString"
[ https://issues.apache.org/jira/browse/PHOENIX-2887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15281649#comment-15281649 ]
Nick Dimiduk commented on PHOENIX-2887:
---------------------------------------
Thanks a lot for the quick patch, I'll take it for a spin.
I think this bug is severe enough that it warrants a 4.7.1 release. Basically, we can't use MR on distributed clusters with out it.

> Uberjar applications operating over Phoenix 4.7.0 are expressing the same symptoms as MR jobs from HBASE-11118. Looks like PHOENIX-2417 introduced direct use of {{ZeroCopyLiteralByteString}}, which causes those problems. We need to replace use of that class with {{org.apache.hadoop.hbase.util.ByteStringer}}. We should probably consider also doing as HBase did, adding a pre-commit check for this "toxic" class so that it doesn't sneak in again.
