Brian Bockelman commented on HADOOP-4775:
-----------------------------------------

I have found quite a few more processes which are stuck on the NewByteArray 
method.  We're trying to increase the available memory in LIBHDFS_OPTS; we'll 
post if this fixes things.

> FUSE crashes reliably on 0.19.0
