> HBASE-19435 implements a fix for reopening file channels when they are unnexpected closed
> to avoid disabling the BucketCache. However, it was missed that the the channels might not
> actually be completely closed (the write or read channel might still be open
> (see https://docs.oracle.com/javase/7/docs/api/java/nio/channels/ClosedChannelException.html)
> This commit closes any open channels before creating a new channel.
