Hive fails to start with "Caused by: java.lang.NoClassDefFoundError: com/ongres/scram/common/stringprep/StringPreparation"

Hi,

we installed a CDP Private Cloud 7.1.9 cluster (CM 7.11.3) on AWS ec2 machines with Postgres RDS as backend database.

Hive Metastore Server is on two machines:

  • ap-cdpclusteru1c (role group: Hive Metastore Server Default Group)
  • ap-cdpclusteru2c. (role group: hive-HIVEMETASTORE)

Configuration in CM looks identical for both Roles

ap-cdpclusteru1c starts successfully but ap-cdpclusteru2c fails to start with following error:

Full log attached.

I scanned the jars to search for StringPreparation.class and it has the same results on both machines:

 

jars$ ls *.jar | while read jar ; do unzip -l $jar | sed -e 's@^@'$jar' @' | grep '\.class$' ; done | awk '/StringPreparation.class/ { print $1, $NF }'
config-service-1.0.0.7.1.9.6-3.jar org/postgresql/shaded/com/ongres/scram/common/stringprep/StringPreparation.class
config-service.jar org/postgresql/shaded/com/ongres/scram/common/stringprep/StringPreparation.class
postgresql-42.5.1.jar org/postgresql/shaded/com/ongres/scram/common/stringprep/StringPreparation.class
storage-tool-0.10.0.7.1.9.6-3.jar org/postgresql/shaded/com/ongres/scram/common/stringprep/StringPreparation.class
storage-tool-2.3.0.7.1.9.6-3.jar org/postgresql/shaded/com/ongres/scram/common/stringprep/StringPreparation.class

 

Looks like "com/ongres/scram/common/stringprep/StringPreparation.class" is not present anywhere, only the "org/postgresql/shaded/com/ongres/scram/common/stringprep/StringPreparation.class" is present.

There is RH8 and Java 11 on both machines:

ap-cdpclusteru2c ~$ java --version
openjdk 11.0.22 2024-01-16 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.22.0.7-1) (build 11.0.22+7-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.22.0.7-1) (build 11.0.22+7-LTS, mixed mode)

How can I fix the issue causing this error?

During cluster installation we followed the postgresql jdbc instruction:
https://docs.cloudera.com/cdp-private-cloud-base/7.1.9/installation/topics/cm_postgres_jdbc_installa...
later, when fixing some issues, we removed the /usr/share/java/postgresql-connector-java.jar on u1c.
It stayed on u2c and turned to be problem.
It is default name, so hive process was picking it up:

+ JDBC_JARS=/usr/share/java/mysql-connector-java.jar:/usr/share/java/postgresql-connector-java.jar:/usr/share/java/oracle-connector-java.jar


and trying to use.
When we removed it on u2c, hive process started to to take 'cloudera delivered' jar:

+ JDBC_JARS=/usr/share/java/mysql-connector-java.jar:/opt/cloudera/cm/lib/postgresql-42.5.1.jar:/usr/share/java/oracle-connector-java.jar

and hive could start successfully.

We compared the jars, and seems that 'bad' jar was in version 42.2, good one was 42.5:

$ unzip _postgresql-connector-java.jar -d bad
$ cat bad/META-INF/MANIFEST.MF | grep -i Version
Manifest-Version: 1.0
Implementation-Version: 42.2.14
JavaPackages-Version: 42.2.14
Specification-Version: 4.2

$ unzip postgresql-42.5.1.jar -d good
$ cat good/META-INF/MANIFEST.MF | grep -i Version
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Version: 42.5.1
...
Specification-Version: 4.2

 

Listing of jar contents confirms that the class was missing in jar that we used.

$ unzip -l _postgresql-connector-java.jar | grep com/ongres/scram/common/stringprep/StringPreparation.class
$ unzip -l postgresql-42.5.1.jar | grep com/ongres/scram/common/stringprep/StringPreparation.class
296 02-01-1980 00:00 org/postgresql/shaded/com/ongres/scram/common/stringprep/StringPreparation.class

 

Why is this needed on CM host:
https://docs.cloudera.com/cdp-private-cloud-base/7.1.9/installation/topics/cm_postgres_jdbc_installa...
if we removed it and all works as expected on CM host?

Thanks @ldylag for sharing the details, that makes sense.

The CM does not necessarily need the PostgreSQL driver to be installed, of course it's needed only when that database type is configured for CM. The one under the "/opt/cloudera/cm/lib" might be shipped to support the "embedded" database, that might have caused a confusion here (if one HMS is on the CM host), but in general the DB drivers are expected to be under the "/usr/share/java".

Cheers
