Subject [jira] [Commented] (HBASE-13787) use a cli argument parsing library instead of ad-hoc string handling
Date Thu, 28 May 2015 23:33:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14563891#comment-14563891
] 

Gabor Liptak commented on HBASE-13787:
--------------------------------------

In examples:

org.apache.hadoop.hbase.client.example.BufferedMutatorExample uses org.apache.hadoop.util.ToolRunner
which uses org.apache.hadoop.util.GenericOptionsParser which uses org.apache.commons.cli.CommandLine

org.apache.hadoop.hbase.mapreduce.IndexBuilder uses org.apache.hadoop.util.GenericOptionsParser
which uses org.apache.commons.cli.CommandLine, and reads two other parameters directly from
args

org.apache.hadoop.hbase.mapreduce.SampleUploader uses org.apache.hadoop.util.GenericOptionsParser
which uses org.apache.commons.cli.CommandLine, and reads two other parameters directly from
args

org.apache.hadoop.hbase.thrift.DemoClient parses arguments directly

org.apache.hadoop.hbase.thrift.HttpDoAsClient parses arguments directly

org.apache.hadoop.hbase.thrift2.DemoClient parses arguments directly

> several of our mapreduce based tools manually parse strings or rely on system properties
for hteir configuration. update all to use the same cli argument parsing library.
> The particular library used isn't important, but it should be one we already bring in
for some other reason.
> If possible try to make the arguments consistent across all the tools, since you'll be
looking broadly.
