Yi Liu commented on HDFS-7243:
------------------------------
Hi Charles, I was going to commit this patch just now, but found another issue,
sorry for missing that in previous comments.
{code}
dir.getINodesInPath4Write(target, true);
{code}
we should call
{code}
dir.getINodesInPath4Write(target);
{code}
Since the later will hold the FsDir read lock.
Besides, another small nits in the test,
{code}
fs.concat(new Path(ez, "target"), new Path[] { src1, src2 });
{code}
We could use {{target}} instead of {{new Path(ez, "target")}}
> HDFS concat operation should not be allowed in Encryption Zone
