Subject Re: HRegionServer: error opening region
Date Thu, 24 Jul 2008 19:23:55 GMT
I have tried the patch.
The result looks bad. An ArrayIndexOutOfBoundsException is thrown in 
v5.HColumnDescriptor.readFields at the following line:
this.compressionType = CompressionType.values()[ordinal];

Here is the log of the upgrade procedure:
