[jira] [Commented] (KYLIN-1659) NoServerForRegionException in
"Convert Cuboid Data to HFile" step
[ https://issues.apache.org/jira/browse/KYLIN-1659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15273982#comment-15273982 ]
wangxianbin commented on KYLIN-1659:
------------------------------------
hey guys! I guess it's caused by hbase compatible issue, when I downgrade hbase from hbase-0.98.19 to hbase-0.98.8, there is no such issue. so I think it not caused by kylin, I choose to close this ticket.
howerver, there is something, I'd like to share:
with this error, there is many unusual debug info in hbase log, which is "regionserver.HRegionFileSystem: No StoreFiles for: hdfs:", just like this url: http://mail-archives.apache.org/mod_mbox/hbase-user/201604.mbox/%3CCAKKbPbKL7qowj4VRZaiPa9OUJid7w3EBqh3xhGenEtaEhSHFYQ@mail.gmail.com%3E

> error happen to cube building which is generated by "sample.sh" script, hbase can be accessed through hbase shell normally, is this maybe a encoding issue? error as bellow:
