Tsz Wo Nicholas Sze commented on HDFS-7358:
-------------------------------------------
Since the clients still get stuck with wait-timeout, it seems that there is no
one releasing arrays so that clients have to wait. The "wake up: [131072:
10000/10000, free=0]: wait ..." messages just say that the allocate call wakes
up, checks allocations# (but still full) and then sleep again.
[~stack], do you know why the clients are not releasing arrays?
