> When Sqoop runs in test mode it creates another ClassLoader that loads from the generated
JAR file in addition to everything else currently on the classpath (see: com.cloudera.sqoop.util.ClassLoaderStack#addJarFile)
so it is dependent of Thread.currentThread().getContextClassLoader() value.
> However in HCatalog test cases Sqoop invokes org.apache.hive.hcatalog.cli.HCatCli#main
method directly in process (org.apache.sqoop.mapreduce.hcat.SqoopHCatUtilities#executeHCatProgramInProcess)
which can override the contextClassLoader in the current thread and cause the tests to fail.
> The task is to improve org.apache.sqoop.mapreduce.hcat.SqoopHCatUtilities#executeHCatProgramInProcess
to make sure that the class loader used before invoking HCatCli is restored after the main
method of the CLI is finished.
