Hi Team, I am trying to use hbase 0.98 distributed mode with zk 3.4.6 & hadoop ha 2.6.(JDK 1.8) I am having following issue and little help in google pages also I tried to start zk first after clearing zk data dir and tried to start master first and rs later and no luck I used mycluster/hbase in hbase-site.xml and no luck to me.tried to put hdfs-site.xml/core-site.xml in $Hbase_home/conf also. I noticed all hadoop.*jars in $HBASE_HOME/lib are 2.2 of hadoop where as we are using 2.6 and tried to copy those hadoop jars ..but no luck. A New new error is coming:
hbase(main):002:0> create 'cars', 'vi' ERROR: java.io.IOException: Table Namespace Manager not ready yet, try again later at org.apache.hadoop.hbase.master.HMaster.getNamespaceDescriptor(HMaster.java:3179) at org.apache.hadoop.hbase.master.HMaster.createTable(HMaster.java:1735) at org.apache.hadoop.hbase.master.HMaster.createTable(HMaster.java:1774) at org.apache.hadoop.hbase.protobuf.generated.MasterProtos$MasterService$2.callBlockingMethod(MasterProtos.java:40470) at org.apache.hadoop.hbase.ipc.RpcServer.call(RpcServer.java:2027) at org.apache.hadoop.hbase.ipc.CallRunner.run(CallRunner.java:98) at org.apache.hadoop.hbase.ipc.FifoRpcScheduler$1.run(FifoRpcScheduler.java:74) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)ZK are running on 3 servers.I tired to stop hbase and then stopped zk in 3 clusters and cleared zk data and started fresh. My bash_profile on classpath:export CLASSPATH=$CLASSPATH:/home/hadoop/hadoop-2.6.0/lib/*:.export CLASSPATH=$CLASSPATH:/home/hadoop/hbase-0.98.4/lib/*:. my hbase_site.xml <property> <name>hbase.rootdir</name> <value>hdfs://mycluster/hbase</value> </property> <property> and hadoop core-site is same. Any incompatibility between JDK1.8 with hbase or hadoop 2.6? Please suggest any solution. Thanks,Sridhar
