Sqoop command is failing for Oracle database on CDP 7.1.9 cluster and same command works on different cluster of same version

Sqoop command is failing for Oracle database on CDP 7.1.9 cluster and same command works on different cluster of same version

The only difference between working and non-working is storage, it might not be the main issue.

sqoop command: sqoop import -libjars ./ojdbc8.jar -Doracle.jdbc.defaultNChar=true -Doracle.jdbc.OracleConnection.CONNECTION_PROPERTY_SET_ROW_PREFETCH_SIZE=10 -Doracle.jdbc.timezoneAsRegion=false -Doracle.sessionTimeZone=Asia/Kolkata -Doracle.jdbc.NLS_LANG=AMERICAN_AMERICA.AL32UTF8 -Doracle.jdbc.timezoneAsRegion=false --connect jdbc:oracle:thin:@hostname:1522:servicename --password $password --map-column-java CHAR_COL=String,DATE_COL=String,FLOAT_COL=Double,TIMESTAMP_COL=String,VARCHAR_COL=String,VARCHAR2_COL=String,NUMPERPS_COL=String,LONG_COL=String --username $username --as-avrodatafile --split-by FLOAT_COL --mapreduce-job-name SQOOP_SOURCE --columns CHAR_COL,DATE_COL,FLOAT_COL,TIMESTAMP_COL,VARCHAR_COL,VARCHAR2_COL,NUMPERPS_COL,LONG_COL --delete-target-dir --table SQOOP_SOURCE --target-dir hdfs://nameservice1/tmp/SPARK

we tried removing "-Doracle.jdbc.NLS_LANG=AMERICAN_AMERICA.AL32UTF8" from cluster node and still facing same issue.

@Pratibha123

ORA-12705 - This is the key error. The Oracle JDBC driver needs to set up a language and character set session with the Oracle database. To do this, it attempts to read NLS configuration data from files on the local filesystem of the machine where Sqoop is running. This error occurs because it cannot find or access those NLS data files, or the environment variable that points to them is invalid.

ORA-00604: This is a cascading error. It means an internal, recursive SQL statement that Oracle runs during the connection/session setup failed, because the session setup itself was incomplete.

"oracle.jdbc.NLS_LANG" Is not seems to be valid property.

Can you export it before running the job and check?

> export NLS_LANG="AMERICAN_AMERICA.AL32UTF8"

Ensure libjars has the correct ojdbc8.jar and it's compatible with your Oracle DB version.

We tried above suggested solution. ie setting "export NLS_LANG="AMERICAN_AMERICA.AL32UTF8"

But still we are facing the same issue.
