[jira] [Updated] (HBASE-10061) TableMapReduceUtil.findOrCreateJar calls updateMap(null, ) resulting in thrown NPE

     [ https://issues.apache.org/jira/browse/HBASE-10061?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Amit Sela updated HBASE-10061:
------------------------------

    Attachment: HBASE-10061.patch

I'm adding a patch to check if jar is null or empty in updateMap and to return null instead of throwing Exception in case jar was not found.

> jar = getJar(my_class);
> updateMap(jar, packagedClasses);
> In case getJar returns null, updateMap will throw NPE.
> Should check null==jar before calling updateMap.
