Anu Engineer updated HDFS-11492:
--------------------------------
Attachment: HDFS-11492-HDFS-7240.003.patch
Thank you for your comments [~xyao]. The new patch addresses all comments
except one.
bq. Line 622-632: NIT: a good candidate to use JDK8 stream/filter/map?
fixed.
bq. Line 276: NIT: typo in commandProcessThead
fixed.
bq. Line 280: should we limit the maximum restart attempts?
I am very reluctant to do this, because we have no safe way of only disabling
this thread. That is if statemachine is running, we must have command processor
also running. The hope is that if we get errors in some handler, that handler
will handle it correctly and set the shutdown flag for errors which are not
recoverable. if the unhandledException handler is getting run, that is probably
a Bug. We can add a counter to monitor this condition in data nodes via JMX
later.
