Subject Re: Hive Table feed replication is not working
Date Wed, 23 Apr 2014 08:39:18 GMT
Hi Sunil,

Looks like an issue if the feed doesn't have timed partitions. Have created
https://issues.apache.org/jira/browse/FALCON-410 to track this

Meanwhile, you can define a feed with timed partitions and it should work.

<table uri="catalog:default:in_table#ds=${YEAR}-${MONTH}-${DAY}-${HOUR}-${MINUTE}"
