Subject [jira] [Updated] (SQOOP-3250) IndexOutOfBoundsException exceptions in SqoopClient
Date Thu, 02 Nov 2017 12:16:02 GMT

     [ https://issues.apache.org/jira/browse/SQOOP-3250?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Colm O hEigeartaigh updated SQOOP-3250:
---------------------------------------
    Description: 
There are a bunch of potential IndexOutOfBoundsException exceptions in SqoopClient, caused
by returning .get(0) on a list which could potentially be empty. 

In particular, there is a problem with reading a Job, if the caller does not have the permission
to read the given Job. Previous Sqoop versions returned an exception, but 1.99.7 returns an
empty list, leading to a NPE.
