How to disable hive CLI for all the users . Planning to use "beeline" instead of hive CLI

paramesh787 — Fri, 08 Jul 2016 01:39:42 GMT

Currently we are using Hive CLI on my cluster,For the security purpose we planned to use "beeline" by disabling "Hive CLI" from the existing cluster. I have added the lines below in hive-env template thru ambari to disable the hive shell

if["$SERVICE"="cli"];then

echo "Sorry! I have disabled hive-shell"

exit1

Once I restarted the hive service I could see 2 CRIT alerts from ambari "Hive Metastore process cannot be determined to be up and listening on the network."

I know that I can revoke execute permission for below file on all hive-clients.

/usr/hdp/current/hive-client/bin/hive

Could someone suggest me the better approach to disable "Hive CLI" .

@Parameswara Nangi

if [ "$SERVICE" = "cli" ] && [ "$USER" != "ambari-qa" ]; then 
echo "Sorry! hive cli has been disabled for security purpose, please use beeline instead." 
exit 1 
fi

This gives ambari-qa the hive cli access and therefore the hive metastore health check passes.

Hi Sandeep,

Thank you very much for the prompt response..

I have added the above lines to hive-env template and restarted the hive services and it worked, the error was disappeared from from ambari.

Connected to beeline thru backend submitted a query and it was executed . but I could see the below error.

ERROR hdfs.KeyProviderCache: Could not find uri with key [dfs.encryption.key.provider.uri] to create a keyProvider !!

Please suggest me on this.
