Subject MetaData picked as NULL upon restarting topology - trident
Date Tue, 30 Dec 2014 08:47:57 GMT

I am working with a storm trident topology and using hbase as the spout. Am
using ITridentSpout for the spout specification. The initializeTransaction
method contains the prevMetaData and currMetaData as parameters. When I
kill and submit the topology again, the transaction id is picked correctly,
but both prevMetaData and currMetaData are NULL in the
initializeTransaction method because of which I am unable to proceed with
the last left transaction.

Can someone help me ?

Thanks !
