stack updated HBASE-10156:
--------------------------
Attachment: 10156v6.txt
Fix deadlock, javadoc, and long lines. I removed the updateLock. Seemed odd
taking a lock every time we wanted to append. Rather, did a more involved
little dance around lock rolling halting the writer while the WAL is swapped
out under it.
> Fix up the HBASE-8755 slowdown when low contention
