[jira] [Updated] (KYLIN-3035) How to use Kylin on EMR with S3 as
hbase storage
[ https://issues.apache.org/jira/browse/KYLIN-3035?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shawn Wang updated KYLIN-3035:
------------------------------
Description:
Can somebody give an example of how to use kylin on EMR with S3 as hbase storage, which support reuse the previously built cube on new EMR after the original EMR has been terminated.
My purpose is simple:
1. use transient EMR cluster to build cubes
2. use a persistent cluster to handle query requests
Of course, the culsters should share same hbase storage, so I setup the cluster to use S3 as hbase storage, after 2.2.0 fix the "HFile not written to S3" issue, I have been built a sample cube successfully, using configurations:
EMR:
{noformat}
[
{
"Classification": "hbase-site",
"Properties": {
"hbase.rootdir": "s3://kylin-emrfs/hbase-production"
}
},
{
"Classification": "hbase",
"Properties": {
"hbase.emr.storageMode": "s3"
}
},
{
"Classification": "emrfs-site",
"Properties": {
"fs.s3.consistent": "true",
"fs.s3.consistent.metadata.tableName": "KylinEmrFSMetadata"
}
}
]
{noformat}
kylin.propertities:
{noformat}
kylin.env.hdfs-working-dir=s3://kylin/kylin-emrfs/kylin-working-dir
kylin.server.mode=all
{noformat}
Then I create a new cluster with same EMR configuration and query mode for kylin, kylin just can't startup with errors:

And if I change the Kylin server mode to all, Kylin can startup, but the page on port 7070 can not be opened, with similar errors as above.
I am wondering If there are some other configuration I have missed, or I am just in the wrong way.
It'll be many thanks if someone can give an complete example to show how to get this work done!
