LD_LIBRARY_PATH can't be found

Question

Hi everybody. When I use https://github.com/cloudera/hue/blob/master/tools/ops/hue_sync_ldap_groups_cron.sh to sync ldap groups with hue on my first cluster it's works fine but when I use on a second cluster I have one error "LD_LIBRARY_PATH can't be found, if you are using ORACLE for your Hue database
then it must be set, if not, you can ignore
export LD_LIBRARY_PATH=/path/to/instantclient". Cause this error, we can't retreive de ldap_config used later in the scripts. Does someone know how to fix this issue. Thanks 😉

It was a python version issue between the 2 clusters

Seems like you do not have the below 2 global parameters exported in the problematic cluster Hue node and these libraries are needed to sync LDAP users into Hue DB when you use an Oracle DB as a backend database to Hue.

To check that please run the below command in the Hue node

>> $ echo $ORACLE_HOME

>> $ echo $LD_LIBRARY_PATH

If the above 2 commands return no values then the error that you hitting is expected.

Please export these 2 parameters in the Hue hosted node.

>> log in to the Hue node say for example with the root user

>> Find the path where you have instantclient installed

>> $locate instantclient

>> Copy the instantclient path from the above command and replace it with /path/instantclient in the below command

>> $ export ORACLE_HOME=</path/instantclient>

>> Check again if you can see the value

>> $ echo $ORACLE_HOME

>> Then export the LD library path by running

>> $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib

>>Check again if you can see the value

>> $ echo $LD_LIBRARY_PATH

>> Then try to sync ldap groups again with hue and share your observations.
