I tried using phoenix in hBase with Transparent Encryption of Data At Rest enabled ( AES encryption) 

Works fine for a table with primary key column.

But it doesn't work if I create Secondary index on that tables.I tried to dig deep into the problem and found WAL file encryption throws exception when I have Global Secondary Index created on my mutable table.
Following is the error I was getting on one of the region server.

I had to disable WAL encryption, and it started working fine with secondary Index. So Hfile encryption works with secondary index but WAL encryption doesn't work.

Parking this here for later investigation. For now I'm going to assume this is something in SecureWALCellCodec that needs looking at, but if it turns out to be a Phoenix indexer issue I will move this JIRA there.
