1. I checked the memory size which is 16G. 2. Hadoop version with Hadoop 2.6.0-cdh5.4.4, it's the local hadoop version, use command install_local_hadoop, it's a single node. 3.

If it's Cloudera, check your HBase role groups. You can only have one (the default group). Thanks!

The error is posted during initializing Trafodion, the HBase’s interface create() can’t be invoked, please focus on the following log info. <image001.png> I go to check the idle process HMaster whether run or not, the following is my attached figure. <image002.png> Go through this file, HBase is running correctly. So I try to “initialize trafodion, drop” and go to reinitialize trafodion, it still can’t pass with this error, and try many times. Please give some advice if you guys solve this problem. Thanks Swayer
