…ed snapshot and logs Summary: This is a tool used to check the integrity of downloaded files, it will check: 1. whether the logs file covers the last zxid of snapshot 2. whether the logs file are continuous Since we don't know last processed zxid during epoch changing, we can not verify whether there is data missing or not during epoch changing, in the future we may rely on the digest hash to verify the integrity in ZooKeeper itself when loading data. Test Plan: Download the latest snapshot: $ buck-out/dev/gen/zeus/tools/backup_manager.par download -d ~/temp/data_dir -s snapshot.2a001a34d0.snappy -e zeus-globalwo-49 hdfs -p hdfs://dw-snc1-dfsiron.VOL6:9000/namespace/zeus_test/ Build the tool and check the integrity: $ buck build src/contrib/fatjar: $ buck-out/gen/src/contrib/fatjar/zkcli/zkcli --x datadirCheck ~/temp/data_dir Output: the data in data_dir is intact, last zxid is: 0x2e00bf84bc Reviewers: #zeus, jdb, br33d, nixon Reviewed By: nixon Subscribers: nixon, zeus-diffs@, suhas, thom Differential Revision: https://phabricator.intern.facebook.com/D4188770 Tasks: 14043038, 14409213 Signature: t1:4188770:1480963033:8e528317bbd67d6ed9a6ca6cebad35caa87582ee

Use IZooKeeper instead of ZooKeeper directly to permit mocking.
