ACCUMULO-1755: Modified TSBW so that all client threads will not blocâ¦
I ditched review board and went back to the drawing board.
Before this change all client threads that were adding mutations to a
BatchWriter would block
when the mutations needed to be written to the tablet servers. This change
gives each client
thread their own MutationWriter object using a ThreadLocal. With this
change only one client
should block on adding the mutations to the sendThreadPool object, and
allows the other client
threads to push mutations onto a new MutationSet.
