[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: {noformat} 2017-11-13 07:33:44,415 INFO [main-SendThread(ip-172-31-1-10.cn-north-1.compute.internal:2181)] zookeeper.ClientCnxn:876 : Socket connection established to ip-172-31-1-10.cn-north-1.compute.internal/172.31.1.10:2181, initiating session 2017-11-13 07:33:44,422 INFO [main-SendThread(ip-172-31-1-10.cn-north-1.compute.internal:2181)] zookeeper.ClientCnxn:1299 : Session establishment complete on server ip-172-31-1-10.cn-north-1.compute.internal/172.31.1.10:2181, sessionid = 0x15fb4173c100156, negotiated timeout = 4 2017-11-13 07:33:48,380 DEBUG [main] hbase.HBaseConnection:279 : HTable 'kylin_metadata' already exists Exception in thread "main" java.lang.IllegalArgumentException: Failed to find metadata store by url: kylin_metadata@hbase at org.apache.kylin.common.persistence.ResourceStore.createResourceStore(ResourceStore.java:89) at org.apache.kylin.common.persistence.ResourceStore.getStore(ResourceStore.java:101) at org.apache.kylin.rest.service.AclTableMigrationTool.checkIfNeedMigrate(AclTableMigrationTool.java:94) at org.apache.kylin.tool.AclTableMigrationCLI.main(AclTableMigrationCLI.java:41) Caused by: org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after attempts=1, exceptions: Mon Nov 13 07:33:48 UTC 2017, RpcRetryingCaller{globalStartTime=1510558428667, pause=100, retries=1}, java.net.ConnectException: 拒绝连接 at org.apache.hadoop.hbase.client.RpcRetryingCaller.callWithRetries(RpcRetryingCaller.java:159) at org.apache.hadoop.hbase.client.HTable.get(HTable.java:864) at org.apache.hadoop.hbase.client.HTable.get(HTable.java:830) at org.apache.kylin.storage.hbase.HBaseResourceStore.internalGetFromHTable(HBaseResourceStore.java:385) at org.apache.kylin.storage.hbase.HBaseResourceStore.getFromHTable(HBaseResourceStore.java:363) at org.apache.kylin.storage.hbase.HBaseResourceStore.existsImpl(HBaseResourceStore.java:116) at org.apache.kylin.common.persistence.ResourceStore.exists(ResourceStore.java:144) at org.apache.kylin.common.persistence.ResourceStore.createResourceStore(ResourceStore.java:84) ... 3 more Caused by: java.net.ConnectException: 拒绝连接 at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:717) at org.apache.hadoop.net.SocketIOWithTimeout.connect(SocketIOWithTimeout.java:206) at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:531) at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:495) at org.apache.hadoop.hbase.ipc.RpcClientImpl$Connection.setupConnection(RpcClientImpl.java:416) at org.apache.hadoop.hbase.ipc.RpcClientImpl$Connection.setupIOstreams(RpcClientImpl.java:722) at org.apache.hadoop.hbase.ipc.RpcClientImpl$Connection.writeRequest(RpcClientImpl.java:909) at org.apache.hadoop.hbase.ipc.RpcClientImpl$Connection.tracedWriteRequest(RpcClientImpl.java:873) at org.apache.hadoop.hbase.ipc.RpcClientImpl.call(RpcClientImpl.java:1244) at org.apache.hadoop.hbase.ipc.AbstractRpcClient.callBlockingMethod(AbstractRpcClient.java:227) at org.apache.hadoop.hbase.ipc.AbstractRpcClient$BlockingRpcChannelImplementation.callBlockingMethod(AbstractR
