Florian Verhein commented on SPARK-3185: ---------------------------------------- Sure [~grzegorz-dubicki]. You need to build with the correct version profiles. See for example: https://github.com/florianverhein/spark-ec2/blob/packer/spark/init.sh https://github.com/florianverhein/spark-ec2/blob/packer/tachyon/init.sh Note that I'm using Hadoop 2.4.1 (which I install on the image). > SPARK launch on Hadoop 2 in EC2 throws Tachyon exception when Formatting > JOURNAL_FOLDER > --------------------------------------------------------------------------------------- > > Key: SPARK-3185 > URL: https://issues.apache.org/jira/browse/SPARK-3185 > Project: Spark > Issue Type: Bug > Affects Versions: 1.0.2 > Environment: Amazon Linux AMI > [ec2-user@ip-172-30-1-145 ~]$ uname -a > Linux ip-172-30-1-145 3.10.42-52.145.amzn1.x86_64 #1 SMP Tue Jun 10 23:46:43 > UTC 2014 x86_64 x86_64 x86_64 GNU/Linux > https://aws.amazon.com/amazon-linux-ami/2014.03-release-notes/ > The build I used (and MD5 verified): > [ec2-user@ip-172-30-1-145 ~]$ wget > http://supergsego.com/apache/spark/spark-1.0.2/spark-1.0.2-bin-hadoop2.tgz > Reporter: Jeremy Chambers > > {code} > org.apache.hadoop.ipc.RemoteException: Server IPC version 7 cannot > communicate with client version 4 > {code} > When I launch SPARK 1.0.2 on Hadoop 2 in a new EC2 cluster, the above tachyon > exception is thrown when "Formatting JOURNAL_FOLDER". > No exception occurs when I launch on Hadoop 1. > Launch used: > {code} > ./spark-ec2 -k spark_cluster -i /home/ec2-user/kagi/spark_cluster.ppk > --zone=us-east-1a --hadoop-major-version=2 --spot-price=0.0165 -s 3 launch > sparkProd > {code} > {code} > ----log snippet---- > Formatting Tachyon Master @ ec2-54-80-49-244.compute-1.amazonaws.com > Formatting JOURNAL_FOLDER: /root/tachyon/libexec/../journal/ > Exception in thread "main" java.lang.RuntimeException: > org.apache.hadoop.ipc.RemoteException: Server IPC version 7 cannot > communicate with client version 4 > at tachyon.util.CommonUtils.runtimeException(CommonUtils.java:246) > at tachyon.UnderFileSystemHdfs.<init>(UnderFileSystemHdfs.java:73) > at tachyon.UnderFileSystemHdfs.getClient(UnderFileSystemHdfs.java:53) > at tachyon.UnderFileSystem.get(UnderFileSystem.java:53) > at tachyon.Format.main(Format.java:54) > Caused by: org.apache.hadoop.ipc.RemoteException: Server IPC version 7 cannot > communicate with client version 4 > at org.apache.hadoop.ipc.Client.call(Client.java:1070) > at org.apache.hadoop.ipc.RPC$Invoker.invoke(RPC.java:225) > at com.sun.proxy.$Proxy1.getProtocolVersion(Unknown Source) > at org.apache.hadoop.ipc.RPC.getProxy(RPC.java:396) > at org.apache.hadoop.ipc.RPC.getProxy(RPC.java:379) > at > org.apache.hadoop.hdfs.DFSClient.createRPCNamenode(DFSClient.java:119) > at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:238) > at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:203) > at > org.apache.hadoop.hdfs.DistributedFileSystem.initialize(DistributedFileSystem.java:89) > at > org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:1386) > at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:66) > at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:1404) > at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:254) > at org.apache.hadoop.fs.Path.getFileSystem(Path.java:187) > at tachyon.UnderFileSystemHdfs.<init>(UnderFileSystemHdfs.java:69) > ... 3 more > Killed 0 processes > Killed 0 processes > ec2-54-167-219-159.compute-1.amazonaws.com: Killed 0 processes > ec2-54-198-198-17.compute-1.amazonaws.com: Killed 0 processes > ec2-54-166-36-0.compute-1.amazonaws.com: Killed 0 processes > ---end snippet--- > {code} > *I don't have this problem when I launch without the > "--hadoop-major-version=2" (which defaults to Hadoop 1.x).* -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
