Error:Temporary failure in storage backend

Enviroment:
CDH：5.8.3
Hadoop: Hadoop 2.6
Hbase: 1.2.0

When I run "sh gremlin.sh",It throw exception:
java.lang.RuntimeException: org.janusgraph.diskstorage.TemporaryBackendException: Temporary failure in storage backend

I have no idea with this TemporaryBackendException, has anyone met this before?

Start with the reported `sh gremlin.sh` failure in the CDH 5.8.3, Hadoop 2.6, and HBase 1.2.0 environment. Read `HBaseStoreManager.getDeployment`, `HBaseStoreManager.getFeatures`, and the `JanusGraphFactory.open` stack frames to trace the `TemporaryBackendException`. Done means the cause is identified and the reported startup path no longer fails, with the result documented in the issue.
