Jean-Daniel Cryans commented on HBASE-8420:
-------------------------------------------
The latest patch looks good. Only thing I don't like so much is the handling of
those exceptions since they would bubble up as-is to the client and the
interrupt isn't reset:
{code}
} catch (InterruptedException ie) {
throw new IOException(ie);
} catch (ExecutionException ee) {
throw new IOException(ee);
}
{code}
