Wellington Chevreuil commented on HBASE-22386:
----------------------------------------------

I guess it was something wrong with my local environment, restarted my OS and 
tests are passing now.

> HBOSS: Limit depth that listing locks check for other locks

> treeWriteLock will check all the way up and down the tree for locks. This is 
> more aggressive than it needs to be, and integration testing has shown that 
> there's significant contention when listing tables, and this is one of 
> numerous operations that doesn't need to recursively lock the whole subtree. 
> There's actually a number of operations that only need to lock up or down 1 
> level only, so let's start with listing: non-recursive listings don't need to 
> care about what's going on more than 1 level below them.
