You do not need to add anything to hue.ini (Cloudera Manager configures this for you).

 

Suspect some dependency is not right when you added Hue. Can you delete and add Hue service again with proper dependencies?

Yes and also please share the list of instances you have in the HBase
service in CM.

Hi Romain

 

I have a Cloudera manager 5.2 cluster with one namenode and three datanodes.I have encountered a similar issue (Api Error: TSocket read 0 bytes) while starting hbase in hue.I have followed your blog and have made  required changes but still the issue is not resolved.I have deployed thrift instance and region server for datanode and namenode in hbase.I have tried reinstalling hue but failed. All service are working independently from command line Ex hbase shell,impala-shell etc. Could you please help me to resolve this issue.?

Go to the http://<hueserver>:<port>/desktop/dump_config and in the "Configuration Sections and Variables" section go to hbase and confirm that "hbase_clusters" points to the correct thrift server. If that's not correct, confirm in the Hue service-wide config that you have the Hbase service selected. If that is correct, then go to the Hbase service configuration and check to see if this property is enabled, "Enable HBase Thrift Server Framed Transport".  If it is, try unchecking it and restarting the Hbase thrift server and see if that works.

Thank you CConner. The above solution works. 

I ensured again that the correct Hbase Thrift server was being used. I then went to the Hbase Thrift server Configuration, unchecked the "Enable Hbase Thrift Server Framed Transport" (hbase.regionserver.thrift.framed) and restarted the Thrift server. It was only after this that the "Api socket error" on Hue disappeared and I was able to view the Hbase tables on Hue.

Appreciate all your help! 

 

Regards,

Yogesh

Glad to hear that worked!  Hue doesn't currently support Framed Thrift to Hbase.  It's on the roadmap, but not sure when.

Good to know!

'framed' should work be it would need to be set in the Hue config too:

[hbase]
...

# 'buffered' is the default of the HBase Thrift Server and supports
security.
# 'framed' can be used to chunk up responses,
# which is useful when used in conjunction with the nonblocking server in
Thrift.
## thrift_transport=buffered
