Description

When using IntegrationTestBigLinkedList's Search tools, it always fails since it tries to read WALs in a wrong HBase root dir. Turned out that when initializing IntegrationTestingUtility in IntegrationTestBigLinkedList, its super class HBaseTestingUtility will change hbase.rootdir to a local random dir. It is not wrong since HBaseTestingUtility is mostly used by Minicluster. But for IntegrationTest runs on distributed clusters, we should change it back.
Here is the error info.
