Subject Re: Support of arrays in fields
Date Fri, 19 Apr 2013 21:55:03 GMT
Hi Ruslan,
we tried to do bulk import from Cloudera JIRA instance into ASF instance when we were incubating
Sqoop. Unfortunately we've run into issues, so we decided to keep the Cloudera instance read
only and create corresponding ASF JIRAs on per needed basis. Please check out INFRA-3763 [1]
for more background.
