>                 Key: ACCUMULO-2671
>                 URL:
>             Project: Accumulo
>          Issue Type: Bug
>    Affects Versions: 1.6.0
>            Reporter: Jonathan Park
>             Fix For: 1.6.1, 1.7.0
> This issue mostly came up after a resolution to ACCUMULO-2668 that allows a byte[] to
be passed directly to the underlying stream from the NoFlushOutputStream.
> The problem appears to be due to the BlockedOutputStream.write(byte[], int, int) implementation
that recursively writes out blocks/buffers out. When the stream is passed a large mutation
(128MB was sufficient to trigger the error for me), this will cause a StackOverflowError.

> This is appears to be specifically with encryption at rest turned on.
> A simple fix would be to unroll the recursion.
