Trevor Robinson created HDFS-4115:
-------------------------------------
Summary: TestHDFSCLI.testAll fails one test due to number format
Key: HDFS-4115
URL: https://issues.apache.org/jira/browse/HDFS-4115
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Environment: Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.6.0_35, vendor: Sun Microsystems Inc.
Java home: /usr/lib/jvm/j2sdk1.6-oracle/jre
Default locale: en_US, platform encoding: ISO-8859-1
OS name: "linux", version: "3.2.0-32-generic", arch: "amd64", family: "unix"
Reporter: Trevor Robinson
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.
