-------------------------------
Hi [~sureshms], [~jingzhao] & [~scurrilous],
I ran into this error when running branch-2 TestHDFSCLI. To my surprise this
patch was not ported to branch-2. Could you take a quick look and consider
backporting the patch?
Thanks,
Tony

> This test fails repeatedly on only one of my machines:
> {noformat}
> Failed tests: testAll(org.apache.hadoop.cli.TestHDFSCLI): One of the tests
> failed. See the Detailed results to identify the command that failed
> Test ID: [587]
> Test Description: [report: Displays the report about the Datanodes]
> Test Commands: [-fs hdfs://localhost:35254 -report]
> Comparator: [RegexpComparator]
> Comparision result: [fail]
> Expected output: [Configured Capacity: [0-9]+ \([0-9]+\.[0-9]+
> [BKMGT]+\)]
> Actual output: [Configured Capacity: 472446337024 (440 GB)
> {noformat}
> The problem appears to be that {{StringUtils.byteDesc}} calls
> {{limitDecimalTo2}} which calls {{DecimalFormat.format}} with a pattern of
> {{#.##}}. This pattern does not include trailing zeroes, so the expected
> regex is incorrect in requiring a decimal.
