I want to load data into titan ,which's backend is hbase.So I changed the example from https://github.com/thinkaurelius/titan/blob/titan10/titan-core/src/main/java/com/thinkaurelius/titan/example/GraphOfTheGodsFactory.java a little.But it ocurred many Exceptions when i connect.
Exception in thread "main" com.thinkaurelius.titan.core.TitanException: Could not open global configuration at com.thinkaurelius.titan.diskstorage.Backend.getStandaloneGlobalConfiguration(Backend.java:451) at com.thinkaurelius.titan.graphdb.configuration.GraphDatabaseConfiguration.(GraphDatabaseConfiguration.java:1322) at com.thinkaurelius.titan.core.TitanFactory.open(TitanFactory.java:94) at com.thinkaurelius.titan.core.TitanFactory.open(TitanFactory.java:84) at com.thinkaurelius.titan.core.TitanFactory$Builder.open(TitanFactory.java:139) at titantest.TitanLoad.main(TitanLoad.java:106) Caused by: com.thinkaurelius.titan.diskstorage.TemporaryBackendException: Temporary failure in storage backend at com.thinkaurelius.titan.diskstorage.hbase.HBaseStoreManager.ensureTableExists(HBaseStoreManager.java:759) at com.thinkaurelius.titan.diskstorage.hbase.HBaseStoreManager.ensureColumnFamilyExists(HBaseStoreManager.java:831) at com.thinkaurelius.titan.diskstorage.hbase.HBaseStoreManager.openDatabase(HBaseStoreManager.java:456) at com.thinkaurelius.titan.diskstorage.keycolumnvalue.KeyColumnValueStoreManager.openDatabase(KeyColumnValueStoreManager.java:29) at com.thinkaurelius.titan.diskstorage.Backend.getStandaloneGlobalConfiguration(Backend.java:449) ... 5 more Caused by: org.apache.hadoop.hbase.DoNotRetryIOException: java.lang.IllegalAccessError: tried to access method com.google.common.base.Stopwatch.()V from class org.apache.hadoop.hbase.zookeeper.MetaTableLocator at org.apache.hadoop.hbase.client.RpcRetryingCaller.translateException(RpcRetryingCaller.java:229) at org.apache.hadoop.hbase.client.RpcRetryingCaller.callWithoutRetries(RpcRetryingCaller.java:202) at org.apache.hadoop.hbase.client.ClientScanner.call(ClientScanner.java:299) at org.apache.hadoop.hbase.client.ClientScanner.nextScanner(ClientScanner.java:278) at org.apache.hadoop.hbase.client.ClientScanner.initializeScannerInConstruction(ClientScanner.java:140) at org.apache.hadoop.hbase.client.ClientScanner.(ClientScanner.java:135) at org.apache.hadoop.hbase.client.HTable.getScanner(HTable.java:845) at org.apache.hadoop.hbase.MetaTableAccessor.fullScan(MetaTableAccessor.java:600) at org.apache.hadoop.hbase.MetaTableAccessor.tableExists(MetaTableAccessor.java:364) at org.apache.hadoop.hbase.client.HBaseAdmin.tableExists(HBaseAdmin.java:281) at com.thinkaurelius.titan.diskstorage.hbase.HBaseAdmin1_0.tableExists(HBaseAdmin1_0.java:70) at com.thinkaurelius.titan.diskstorage.hbase.HBaseStoreManager.ensureTableExists(HBaseStoreManager.java:753) ... 9 more Caused by: java.lang.IllegalAccessError: tried to access method com.google.common.base.Stopwatch.()V from class org.apache.hadoop.hbase.zookeeper.MetaTableLocator at org.apache.hadoop.hbase.zookeeper.MetaTableLocator.blockUntilAvailable(MetaTableLocator.java:434) at org.apache.hadoop.hbase.client.ZooKeeperRegistry.getMetaRegionLocation(ZooKeeperRegistry.java:60) at org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation.locateMeta(ConnectionManager.java:1139) at org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation.locateRegion(ConnectionManager.java:1106) at org.apache.hadoop.hbase.client.RpcRetryingCallerWithReadReplicas.getRegionLocations(RpcRetryingCallerWithReadReplicas.java:293) at org.apache.hadoop.hbase.client.ScannerCallableWithReplicas.call(ScannerCallableWithReplicas.java:147) at org.apache.hadoop.hbase.client.ScannerCallableWithReplicas.call(ScannerCallableWithReplicas.java:56) at org.apache.hadoop.hbase.client.RpcRetryingCaller.callWithoutRetries(RpcRetryingCaller.java:200) ... 19 more
Here is the code:
TitanGraph g = TitanFactory.build().set("storage.backend","hbase").set("storage.hostname","192.168.200.121,192.168.200.115")
.set("storage.hbase.table","mytitan").set("storage.hbase.ext.zookeeper.znode.parent","/hbase-unsecure").set("storage.port",2181).open();
BTW,I can connect to the Hbase cluster,it looks fine.
