HDFS 2.7 is default version for HBase 2.0.0. For HBase Stable version, it is, 2.5. I just started HDFS cluster with version 3.1.0. How do I make HBase to use this? I get hsync error message.
EDIT
I am understanding that I have to replace all these jar files? hadoop-*-2.7.4.jar enter image description here
If you refer to Latest compatible version of hadoop and hbase then follow the link provided which is http://hbase.apache.org/book.html#configuration you will see that your combination is not supported yet.
(NT
stands for "Not Tested").
You can also track Hadoop 3 compatibility by watching JIRA HBASE-20540.
