Kazuaki Ishizaki 0b8369d854 [SPARK-14656][CORE] Fix Benchmark.getPorcessorName() always return "Unknown processor" on Linux ... ## What changes were proposed in this pull request? This PR returns correct processor name in ```/proc/cpuinfo``` on Linux from ```Benchmark.getPorcessorName()```. Now, this return ```Unknown processor```. Since ```Utils.executeAndGetOutput(Seq("which", "grep"))``` return ```/bin/grep\n```, it is failed to execute ```/bin/grep\n```. This PR strips ```\n``` at the end of the line of a result of ```Utils.executeAndGetOutput()``` Before applying this PR ```` Java HotSpot(TM) 64-Bit Server VM 1.8.0_66-b17 on Linux 2.6.32-504.el6.x86_64 Unknown processor back-to-back filter: Best/Avg Time(ms) Rate(M/s) Per Row(ns) Relative ------------------------------------------------------------------------------------------- Dataset 472 / 503 21.2 47.2 1.0X DataFrame 51 / 58 198.0 5.1 9.3X RDD 189 / 211 52.8 18.9 2.5X ```` After applying this PR ``` Java HotSpot(TM) 64-Bit Server VM 1.8.0_66-b17 on Linux 2.6.32-504.el6.x86_64 Intel(R) Xeon(R) CPU E5-2667 v2 3.30GHz back-to-back filter: Best/Avg Time(ms) Rate(M/s) Per Row(ns) Relative ------------------------------------------------------------------------------------------- Dataset 490 / 502 20.4 49.0 1.0X DataFrame 55 / 61 183.4 5.5 9.0X RDD 210 / 237 47.7 21.0 2.3X ``` ## How was this patch tested?
