Hi, all, I am trying to build the 2.0 rc3, but can't make it work. I strictly follow the wiki page(http://wiki.apache.org/nutch/Nutch2Tutorial).
Before that, I also ensure that the hbase works well, as: hbase(main):004:0> create 'test1', 'cf' 0 row(s) in 1.3080 seconds The following is what I did and the error I got, Hope you can give me suggestion where I were doing wrong. 1. checkout the code svn co http://svn.apache.org/repos/asf/nutch/tags/release-2.0rc3 2. modify the nutch-default.xml, gora.properties and ivy/ivy.xml as the wiki said. 3. build the code: ant 4. test the code as: tianwei@132:~/nutch-src/release-2.0rc3/runtime/local$ ./bin/nutch inject urls/urls.txt InjectorJob: starting InjectorJob: urlDir: urls/urls.txt InjectorJob: org.apache.gora.util.GoraException: org.apache.hadoop.hbase.ZooKeeperConnectionException: HBase is able to connect to ZooKeeper but the connection closes immediately. This could be a sign that the server has too many connections (30 is the default). Consider inspecting your ZK server logs for that error and then make sure you are reusing HBaseConfiguration as often as you can. See HTable's javadoc for more information. at org.apache.gora.store.DataStoreFactory.createDataStore(DataStoreFactory.java:167) at org.apache.gora.store.DataStoreFactory.createDataStore(DataStoreFactory.java:135) at org.apache.nutch.storage.StorageUtils.createWebStore(StorageUtils.java:69) at org.apache.nutch.crawl.InjectorJob.run(InjectorJob.java:243) at org.apache.nutch.crawl.InjectorJob.inject(InjectorJob.java:268) at org.apache.nutch.crawl.InjectorJob.run(InjectorJob.java:288) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.nutch.crawl.InjectorJob.main(InjectorJob.java:298) Caused by: org.apache.hadoop.hbase.ZooKeeperConnectionException: HBase is able to connect to ZooKeeper but the connection closes immediately. This could be a sign that the server has too many connections (30 is the default). Consider inspecting your ZK server logs for that error and then make sure you are reusing HBaseConfiguration as often as you can. See HTable's javadoc for more information. at org.apache.hadoop.hbase.zookeeper.ZooKeeperWatcher.<init>(ZooKeeperWatcher.java:155) ........... I also tried to switch to use mysql, but also met the IO connection exception. I guess there must be something wrong with my setting. Could you give some suggestions to diagnose and solve this problem? PS, my hbase version is hbase-0.90.5, and in nutch's lib/ directory, there is "hbase-0.90.4", I don't know if it matters or not. The hbase is installed by user "hadoop" and I ran nutch with another user "tianwei", don't know if I need to add something into CLASSPATH or not? Thanks very much. Tianwei
