Deal all.
CM has below query to draw "Total slow get operations across RegionServers"
SELECT integral(total_slow_get_rate_across_regionservers) WHERE entityName = "hbase" AND category = SERVICE
What are the criteria for slow? 1sec ? or hbase.ipc.warn.response.time?
Thanks in advance

Hello. I have configured hue to integrate ldap login. And suceeded 'Test LDAP Configuration' from Hue's Action Menu. But When I try to login with ldap user on hue webui login I failed with 'incorrect username or password'. What should I have to check ? And the login page does not display LDAP select box. Just only displayed username and password box. Thanks.

I tested this again. "Restarting JN which is in the same machine of NN occurs NN fail" was my misunderstanding. The cause of problem is below I thnik. When the JN is restarted, the editlog file known to NN's QJM is no longer available (invalid) You can not record changes to this JN until the edit log is rolled and a new log file is created. After the JN restart, it takes about 3 minutes for the editlog to roll and transition to a usable state. When restarting JN, restart one of them and immediately restart the other. If two JNs can not write, they will stop NN. So, If I restarted JN with interval (about 5 minutes), this can not happen.
