shihuafeng updated HBASE-26209:
-------------------------------
Description:
{{ when i restart hbase cluster,i find edit file loss when wal repaly
.}}
the number of edit files (00000000seqid.tmp to 00000000seqid ) is
31 when split wal to edit. But when i read edits to repaly ,i foud the sum
is 30.
i see rename file is sucessful,but i can not find the edit file .
