yuanxinen updated HBASE-10549:
------------------------------
Description:
First,I explan my test steps.
1.importtsv
2.split the region
3.delete the region info from .META.(make a hole)
4.LoadIncrementalHFiles (this step will hung up in an infinite loop)
I check the log,there are two issues
1.it create _tmp folder in an infinite loop.
hdfs://hacluster/output3/i/_tmp/_tmp/_tmp/_tmp/_tmp/_tmp/test_table,136.bottom
2.when slpliting the hfile,it put the first line data(1211) into two files(top
and bottom)
Input
File=hdfs://hacluster/output3/i/3ac6ec287c644a8fb72d96b13e31f576,outFile=hdfs://hacluster/output3/i/_tmp/test_table,2.top,KeyValue=1211/i:value/1390469306407/Put/vlen=1/ts=0
Input
File=hdfs://hacluster/output3/i/3ac6ec287c644a8fb72d96b13e31f576,outFile=hdfs://hacluster/output3/i/_tmp/test_table,2.bottom,KeyValue=1211/i:value/1390469306407/Put/vlen=1/ts=0
and then I check the code.
So I think before spliting the hfile,we should check the consistency of
startkey and endkey,if something wrong,we should throw the exception,and stop
LoadIncrementalHFiles.
> when there is a hole,LoadIncrementalHFiles will hung up in an infinite loop.
