Can you also send us the server logs during that timeframe?
Thanks. -- Lars ________________________________ From: Pal Konyves <[email protected]> To: [email protected] Sent: Tuesday, March 19, 2013 5:02 PM Subject: HBase client hangs after connecting to Zookeeper in pseudo-mode Hi, I'm new to the list, just registered for this question. I'm setting up HBase in pseudo-distributed mode. I can run the hbase shell locally, and create tables, put some rows, they are present in the HDFS good. However, when I try to connect either from the same machine or the host machine (the HBase setup is on a VM), the client hangs after connecting to ZooKeeper. The console output is: 13/03/20 00:20:36 INFO zookeeper.ClientCnxn: Opening socket connection to server debian-vm/192.168.1.102:2181. Will not attempt to authenticate using SASL (unkn own error) 13/03/20 00:20:36 INFO zookeeper.ClientCnxn: Socket connection established to de bian-vm/192.168.1.102:2181, initiating session 13/03/20 00:20:36 INFO zookeeper.ClientCnxn: Session establishment complete on s erver debian-vm/192.168.1.102:2181, sessionid = 0x13d84e02e920005, negotiated ti meout = 180000 [..then waits forever, then after forever shows:] org.apache.hadoop.hbase.client.NoServerForRegionException: Unable to find regio for stops,,99999999999999 after 10 tries. I checked the following pitfalls: -- My HBase 94.4 build is compatible with my Hadoop 1.0.4 according to HBase documentation -- I put 'vm-debian' (the hostname I want to identify my virtual machine that runs the HBase setup) into the host and virtual machine's /etc/host file to map the hostname nicely (and it works, because browser shows Hadoop and HBase info pages) -- I copied the hadoop related jars from hadoop root and hadoop/lib into HBase/lib (although they were the same version, but I could never know) -- I set up the time on the virtual machine where the HBase setup runs properly, no time shifts -- I checked the logs and web UIs to see every processes are running: Hadoop, HBase master, Zookeeper Environment: HBase install is a Debian 32 bit virtual machine, with JDK 1.7.0_17 Host machine is Windows 7 with JDK 1.7.0_05 but the client program does not work regardless if it's running on the HBase VM or on the host The tiny client is: http://pastebin.com/060Yu2Gz here are the config files: http://pastebin.com/ArVvwU59 Please help and tell me what I do wrong, because it has been driving me crazy for about 3 days, and I'm getting very angry about this whole Hadoop stuff, that I cannot even get running a very basic use-case with it. Thanks, Pal
