Hi there,   Recently, we faced a problem: our Hue can't connect to our Hbase on CDH 6.0.1 Later, we had other task which need python(happyhbase) to do the operation on hbase. We recieved: "No protocol version header error"   Finally, we resolved both problem at same time. First of all, I have to declare this: we opened hbase thrift server before the above two issue happened. Then, the default HBase setting in CM: hbase.regionserver.thrift.http and hbase.thrift.support.proxyuser They was checked. In /etc/hbase/conf/hbase-sit.xml, Their values are "true"   We found a link: https://github.com/wbolster/happybase/issues/161 So, we unchecked both of them. ( In hbase-sit.xml, They become "false" ) And two problems solevd.   I saw a lot people had this issue, I hope my sharing will be helpful.     ... View more
