Shaofeng SHI commented on KYLIN-1899:
-------------------------------------
Check this error message: "Error:
org.apache.hadoop.util.NativeCodeLoader.buildSupportsSnappy()Z"
By default Kylin uses Snappy compression; You need install Hadoop native
libraries; Otherwise, you need disable snappy compression by comment all
configurations in conf/kylin.properties, conf/*.xml (grep snappy).
BTW, JIRA is for bug/task tracking; For QA or discussions please goto Kylin's
mailing list; only when it is confirmed, create JIRA. Thanks.
