gaojinchao commented on HBASE-4739:
-----------------------------------
about test failed:
1.org.apache.hadoop.hbase.io.hfile.TestHFileBlock
Look this comments
public void testBlockHeapSize() {
// We have seen multiple possible values for this estimate of the heap size
// of a ByteBuffer, presumably depending on the JDK version.
assertTrue(HFileBlock.BYTE_BUFFER_HEAP_SIZE == 64 ||
HFileBlock.BYTE_BUFFER_HEAP_SIZE == 80); But in
https://issues.apache.org/jira/browse/HBASE-4768
We add some code snippets：
assertEquals(80, HFileBlock.BYTE_BUFFER_HEAP_SIZE);
long byteBufferExpectedSize =
ClassSize.align(ClassSize.estimateBase(buf.getClass(), true)
+ HFileBlock.HEADER_SIZE + size);
2.org.apache.hadoop.hbase.master.TestDistributedLogSplitting
Because we choose a rs with 0 regions.
// it said that regions is 0.

> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.90.4
> Reporter: Jean-Daniel Cryans
> Assignee: gaojinchao
> Priority: Minor

> I saw this in the aftermath of HBASE-4729 on a 0.92 refreshed yesterday, when
> the master died it had just created the RIT znode for a region but didn't
> tell the RS to close it yet.
> When the master restarted it saw the znode and started printing this:
> {quote}

> It's never going to happen, and it's blocking balancing.
> I'm marking this as minor since I believe this situation is pretty rare
> unless you hit other bugs while trying out stuff to root bugs out.
