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

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

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