I recognize this exception. Assume you are on HBase 1.x right?
java.lang.IllegalArgumentException: Can not create a Path from a null string
at org.apache.hadoop.fs.Path.checkPathArg(Path.java:123)
at org.apache.hadoop.fs.Path.<init>(Path.java:135)
at org.apache.hadoop.fs.Path.<init>(Path.java:89)
See this JIRA for why details: https://issues.apache.org/jira/browse/KYLIN-953
Latest 1.x-HBase1.1.3 does set "hadoop.tmp.dir" and "hbase.fs.tmp.dir"
if they are missing. Try latest code or set the two parameters
manually.
