gaojinchao commented on HBASE-4112: ----------------------------------- False means finished scan. True mean continue and process the next record. In this case , True is better.(my test is also) // the code segment for metaScan. for (Result rr : rrs) { if (processedRows >= rowUpperLimit) { break done; } if (!visitor.processRow(rr)) break done; //exit completely ////////// processedRows++; } > Creating table threw NullPointerException > ----------------------------------------- > > Key: HBASE-4112 > URL: https://issues.apache.org/jira/browse/HBASE-4112 > Project: HBase > Issue Type: Bug > Components: master > Affects Versions: 0.90.3 > Reporter: gaojinchao > Assignee: gaojinchao > Fix For: 0.90.4 > > Attachments: HBASE-4112_branch90V1.patch > > > It happened in latest branch 0.90. but I can't reproduce it. > > > > It seems using api getHRegionInfoOrNull is better or check the input > > parameter before call getHRegionInfo. > > > > Code: > > public static Writable getWritable(final byte [] bytes, final > > Writable w) > > throws IOException { > > return getWritable(bytes, 0, bytes.length, w); > > } > > return getWritable(bytes, 0, bytes.length, w); // It seems input > > parameter bytes is null > > > > logs: > > 11/07/15 10:15:42 INFO zookeeper.ClientCnxn: Socket connection > > established to C4C3.site/157.5.100.3:2181, initiating session > > 11/07/15 10:15:42 INFO zookeeper.ClientCnxn: Session establishment > > complete on server C4C3.site/157.5.100.3:2181, sessionid = > > 0x2312b8e3f700002, negotiated timeout = 180000 [INFO] Create : ufdr111 222! > > [INFO] Create : ufdr111 start! > > java.lang.NullPointerException > > at > > org.apache.hadoop.hbase.util.Writables.getWritable(Writables.java:75) > > at > > org.apache.hadoop.hbase.util.Writables.getHRegionInfo(Writables.java:1 > > 19) > > at > > org.apache.hadoop.hbase.client.HBaseAdmin$1.processRow(HBaseAdmin.java > > :306) > > at > > org.apache.hadoop.hbase.client.MetaScanner.metaScan(MetaScanner.java:1 > > 90) > > at > > org.apache.hadoop.hbase.client.MetaScanner.metaScan(MetaScanner.java:9 > > 5) > > at > > org.apache.hadoop.hbase.client.MetaScanner.metaScan(MetaScanner.java:7 > > 3) > > at > > org.apache.hadoop.hbase.client.HBaseAdmin.createTable(HBaseAdmin.java: > > 325) > > at createTable.main(createTable.java:96) > > -- This message is automatically generated by JIRA.
