Tsz Wo Nicholas Sze commented on HDFS-7358:
-------------------------------------------
[~stack], have you changed dfs.bytes-per-checksum in your test? What is
version of Hadoop?
{code}
2014-11-04 16:55:57,202 DEBUG [sync.0] util.ByteArrayManager: allocate(65565):
count=60367, aboveThreshold, [131072: 9998/10000, free=1], recycled? true
{code}
I wonder why it allocates a 65565 (> 64kB) array. See also HDFS-7308.
