Xiaoyu Yao commented on HDFS-11788:
-----------------------------------

Thanks [~vagarychen] for working on this. Patch v2 looks pretty good to me. I 
only have some minor suggestions:
 
1. Can we use the try-with-resource for {{dbStore}} so that the store can be 
closed even exception is throw in the middle of the insert into sqllite 
{code}
365         LevelDBStore dbStore = new LevelDBStore(dbFile, dbOptions);
{code}

2. Does level db support open by multiple processes? Do we need any special 
Option/flag when opening a live nodepool/container db running with SCM?
If we assume this is an offline tool, we should comment or document it 
somewhere.
