Lars Hofhansl created HBASE-9025:
------------------------------------
Summary: Thread safety issue in MetaScanner
Key: HBASE-9025
URL: https://issues.apache.org/jira/browse/HBASE-9025
Project: HBase
Issue Type: Bug
Affects Versions: 0.94.9
Reporter: Lars Hofhansl
I just saw this in a test run in 0.94:
{code}
Stacktrace
java.lang.NullPointerException
at java.util.TreeMap.getEntry(TreeMap.java:324)
at java.util.TreeMap.get(TreeMap.java:255)
at
org.apache.hadoop.hbase.util.TestHBaseFsck.testSplitDaughtersNotInMeta(TestHBaseFsck.java:1346)
...
{code}
The TreeMap in question here is actually returned from
{{HTable.getRegionLocations()}}, which in turns calls
{{MetaScanner.allTableRegions(getConfiguration(), getTableName(), false);}}
