Samir Ahmic created HBASE-13456:
-----------------------------------
Summary: Improve HFilePrettyPrinter first hbase:meta region processing
Key: HBASE-13456
URL: https://issues.apache.org/jira/browse/HBASE-13456
Project: HBase
Issue Type: Improvement
Components: util
Affects Versions: 0.98.12
Environment: x86_64 GNU/Linux
Reporter: Samir Ahmic
Assignee: Samir Ahmic
Priority: Minor
HFilePrettyPrinter have couple of small issues when -r option is used with hbase:meta region as argument:
1. Processing files in oldWals and recovered.edits directories
{code}
$ hbase org.apache.hadoop.hbase.io.hfile.HFilePrettyPrinter -v -r hbase:meta,,1
Number of region files found -> 3
Found file[1] -> hdfs://P3cluster/hbase/data/hbase/meta/1588230740/info/e1d395908f8c43d2b22bb3a630728ebf
Found file[2] -> hdfs://P3cluster/hbase/data/hbase/meta/1588230740/info/e30faa185198449b9cb2eeb5589ebd1b

{code }
2. If full region name is passed as argument we have wrong encoded region name returned:
{code}
hbase org.apache.hadoop.hbase.io.hfile.HFilePrettyPrinter -v -r hbase:meta,,1.1588230740

{code}
I have modified HFilePrettyPrinter.java to address this issues. Patch is coming soon.
