I was following this http://www.thecloudavenue.com/2013/03/analyse-tweets-using-flume-hadoop-and.html tutorial after collecting the twitter data into hdfs i imported it to a hive tweets table and everything worked fine. But on clicking on browse data, I get this error. Cannot read table Bad status for request TExecuteStatementReq(confOverlay={}, sessionHandle=TSessionHandle(sessionId=THandleIdentifier(secret="\x06{'\xb6\x1d\x13Dx\x90\x86^\xfc\xb6\xf9\\L",
