> I added some debuging to line 511 in HFile.java and found that the column is causing
my problem it was > max size
> we should check this before saving the record to memstore
> As of 0.20.0-RC2 the server dies and cause the hlogs to be read again by the next region
server that gets the region in the end it cause the whole cluster to go down sense the bad
data is in the hlog at this point.
