Ted Yu commented on HBASE-16479:
--------------------------------
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.mapreduce.Mapper.run(Mapper.java:146)

{code}
What's the recommended way to handle WAL from 1.x ?
> Move WALEdit from hbase.regionserver.wal package to hbase.wal package
