Description

Unfortunately, the stack trace I had of the exception was on an AWS cluster that has been reclaimed, so I cannot provide the stack trace, but the exception was in HRegionInfo.readFields

Email from shangsheng -
I did check other logs files under jt01 (where TM0 died) and found some exceptions been thrown from TM recovery thread due to “HRegionInfo.readFields”. However, these troubled statements are NOT in R2.1. I do a comparison between R2.1 and R2.2 (for HBaseTxClient.java) and there are many changes (most of them are exception handling related). These statements accidently show up in R2.2 code (probably get merged in from Trafodion path). I assume JoshuaTree is based on R2.2.
