CLONE - getScanner hangs with some startRows that are found if scanning entire
table
------------------------------------------------------------------------------------
Key: HBASE-5322
URL: https://issues.apache.org/jira/browse/HBASE-5322
Project: HBase
Issue Type: Bug
Affects Versions: 0.18.0, 0.18.1, 0.19.0
Reporter: Karthik Pandian
Priority: Critical
Fix For: 0.18.1, 0.19.0
I have a table with 8 byte binary row keys. There are a a few hundred
thousands rows, each with two families and between 1k and 50k of total data
across about 15 columns.
When attempting to get a scanner using a specified startRow, my client freezes
on the HT.getScanner(cols,row) with no exception ever thrown and no debug
output in any server logs.
If I get a scanner with HT.getScanner(cols) and then iterate through, I will
eventually reach the row I was seeking before successfully.
Some rows can be found, some cannot. At this point I'm not able to distinguish
anything special about the ones that cause the client the hang.
At first I thought this was only a problem with 0.19 trunk as a downgrade to
0.18 resolved the issue for a particular key. However other keys still have
this issue on 0.18 branch.
