@Bilal_Hammas 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.
