Use Hue with Impala in Docker

[Alexsem]

Hello,

I have a few hadoop services running locally in my pc with Docker. I have hdfs and the impala-shell running through the command line without any issues but I am unable to make it run in Hue. 

First of all, Hue is connecting to the HDFS filesystem and I can navigate, upload or delete files in hdfs. I don't have the hive-server2 running but the Impalad is running properly and Hue is configured to connect to it to the port 21050 (the same port that appears when I connect through impala-shell).

When I open the hue with Impala, I get the following errors: 

"Ignoring invalid configuration option: idle_session_timeout"

"Bad status for request TOpenSessionReq(username=u'hue', password=None, client_protocol=6, configuration={'idle_session_timeout': '3600'}): TOpenSessionResp(status=TStatus(errorCode=None, errorMessage='Ignoring invalid configuration option: idle_session_timeout', sqlState='HY000', infoMessages=None, statusCode=3), sessionHandle=TSessionHandle(sessionId=THandleIdentifier(secret='\xc3h\x04\x1a\xde\xd9Ab\xb9b\x0f\xdf\xfe\x83\xe3\x93', guid='\x9e\x98\xe7\xa2\x8c\xa0Jg\x97%\xbaF\x1c\x87\t\x04')), configuration=None, serverProtocolVersion=4)"

This is how my hue.ini looks like:

[hadoop]
 
  [[hdfs_clusters]]
 
    [[[default]]]
 
      # Enter the filesystem uri
      fs_defaultfs=hdfs://hadoop:8020
 
      # Use WebHdfs/HttpFs as the communication mechanism.
      # Domain should be the NameNode or HttpFs host.
      webhdfs_url=http://hadoop:50070/webhdfs/v1

[beeswax]
 
  # Host where HiveServer2 is running.
  hive_server_host=hadoop.ent.com
  
  
[impala]
 
  # Host of the Impala Server (one of the Impalad)
  server_host=hadoop
  server_port=21050

#[desktop]
#app_blacklist=beeswax,security,metastore,spark,indexer,spark,pig,hbase,sqoop,jobbrowser,rdbms,jobsub,zookeeper

[desktop]
	[[auth]]
	# A negative number means that idle sessions will not be timed out.
	idle_session_timeout=-1

I have been going on with this issue for days and I would really like to use the Hue instead of the Impala-shell to make my life easier. Is it mandatory to have the Hive-server2 running to run Impala queries?

First :

- Why do you suspect that Hiveserver2 need to be up and running for impala query to works ? Did you observe that when running Hiveserver2 impala queries worked ?

By the way, Hivemetastore is running right ?

- Second : You should go look at hue server log files. You should see a better error.
