Kai Zheng commented on HDFS-12303:
----------------------------------
Just took a look at the failed unit tests, finding most of them reported the
following line:
{noformat}
at
org.apache.hadoop.hdfs.DFSStripedOutputStream.updatePipeline(DFSStripedOutputStream.java:780)
{noformat}
pointing to this line of code
{code}
Preconditions.checkState(ackedBytes <= sentBytes);
{code}
which is being handled under HDFS-11882.
> Change default EC cell size to 1MB for better performance
