[jira] [Created] (HBASE-19166) Add translation for handling hbase.regionserver.wal.WALEdit

Ted Yu created HBASE-19166:
------------------------------

             Summary: Add translation for handling hbase.regionserver.wal.WALEdit
                 Key: HBASE-19166
                 URL: https://issues.apache.org/jira/browse/HBASE-19166
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Major


For hlog generated by 1.x, using WALPlayer from hbase2 would result in:
{code}
2017-11-02 21:22:40,907 INFO  [main] mapreduce.Job: Task Id : attempt_1509641483571_0003_m_000000_0, Status : FAILED
Error: java.lang.ClassCastException: org.apache.hadoop.hbase.regionserver.wal.WALEdit cannot be cast to org.apache.hadoop.hbase.wal.WALEdit
        at org.apache.hadoop.hbase.mapreduce.WALPlayer$WALCellMapper.map(WALPlayer.java:143)
        at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:146)
        at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:793)
{code}
HBASE-16479 relocated WALEdit.

Chatting with Enis, he mentioned adding translation for handling hbase.regionserver.wal.WALEdit

This way, WAL from 1.x can be recognized by hbase-2
