Upgrade log4j jar file in DVM JDBC driver

The Scenario:

Using the latest DVM JDBC Driver, users issue an import command on Apache Sqoop to do a parquet file conversion.

The Problem:

The error “java.lang.NoSuchMethodError: 'org.apache.logging.log4j.Level org.apache.log4j.helpers.OptionConverter.convertLevel(java.lang.String, org.apache.logging.log4j.Level)” occurs when issuing the following import command on Apache Sqoop:

sqoop import -Dorg.apache.sqoop.splitter.allow_text_splitter=true -Dmapreduce.job.queuename=${queue} --connect "jdbc:${server}" --driver ${driverJDBC} --username ${user} --password ${password} --as-parquetfile --table ${DVMSourceTableName} --split-by ${hivePrimaryColumnName} --hive-database ${hiveDB} --hive-table ${hiveStagingInternaltable} -m ${mapreduce_number} --hs2-url ${beelineString} --outdir java_code_CAMPS/ --delete-target-dir --target-dir ${targetDir}/${hiveStagingInternaltable} --hive-drop-import-delims”

The latest DVM JDBC Driver includes log4j-api-2.17.1 which does not support OptionConverter class.

Current workarounds:

Updating the log4j file on Apache Sqoop to use log4j-api-2.20.0 which contains the OptionConverter method, provides a workaround.

Proposed solutions:

Update the log4j file in the DVM JDBC driver to a more current version that supports the OptionConverter method.
