[jira] [Created] (HADOOP-10556) Add toLowerCase support to auth_to_local rules for service name
Alejandro Abdelnur created HADOOP-10556: --- Summary: Add toLowerCase support to auth_to_local rules for service name Key: HADOOP-10556 URL: https://issues.apache.org/jira/browse/HADOOP-10556 Project: Hadoop Common Issue Type: Improvement Components: security Affects Versions: 2.4.0 Reporter: Alejandro Abdelnur Assignee: Alejandro Abdelnur When using Vintela to integrate Linux with AD, principals are lowercased. If the accounts in AD have uppercase characters (ie FooBar) the Kerberos principals have also uppercase characters (ie FooBar/). Because of this, when a service (Yarn/HDFS) extracts the service name from the Kerberos principal (FooBar) and uses it for obtain groups the user is not found because via Linux the user FooBar is unknown, it has been converted to foobar. -- This message was sent by Atlassian JIRA (v6.2#6252)

[jira] [Created] (HADOOP-10554) Performance: Scan metrics for 2.4 are notably down compared to 0.23.9
patrick white created HADOOP-10554: -- Summary: Performance: Scan metrics for 2.4 are notably down compared to 0.23.9 Key: HADOOP-10554 URL: https://issues.apache.org/jira/browse/HADOOP-10554 Project: Hadoop Common Issue Type: Bug Affects Versions: 2.4.0 Reporter: patrick white Performance comparison benchmarks for Scan test's runtime and throughput metrics are slightly out of 5% tolerance in 2.x compared against 0.23. The trend is consistent across later releases in both lines, latest release numbers are; Runtime: 2.4.0.0 ->73.6 seconds (avg 5 passes) 0.23.9.12 ->69.4 seconds (avg 5 passes) Diff: -5.7% Throughput: 2.4.0.0 -> 28.67 GB/s (avg 5 passes) 0.23.9.12 -> 30.41 GB/s (avg 5 passes) Diff: -6.1% Scan test is specifically measuring the average map's input read performance. The diff is consistent when run on a larger (350 node) perf environment, we are in process of seeing if this reproduces in a smaller cluster, using appropriately scaled inputs. -- This message was sent by Atlassian JIRA (v6.2#6252)
[jira] [Created] (HADOOP-10553) Performance: AM scaleability is 10% slower in 2.4 compared to 0.23.9

The trend is consistent across later releases in both lines, latest release numbers are: 2.4.0.0 runtime 255.6 seconds (avg 5 passes) 0.23.9.12 runtime 230.4 seconds (avg 5 passes) Diff: -9.9% AM Scalability test is essentially a sleep job that measures time to launch and complete a large number of mappers. The diff is consistent and has been reproduced in both a larger (350 node, 100,000 mappers) perf environment, as well as a small (10 node, 2,900 mappers) demo cluster. -- This message was sent by Atlassian JIRA (v6.2#6252)
