I used these commands to show the GC timings : -verbose:gc -XX:-PrintGCDetails -XX:+PrintGCTimeStamps
Following is the output I got on the standard output : 4.092: [GC 4.092: [ParNew: 274752K->27199K(309056K), 0.0421460 secs] 274752K->27199K(995776K), 0.0422720 secs] [Times: user=0.33 sys=0.11, real=0.04 secs] 16.630: [GC 16.630: [ParNew: 301951K->17854K(309056K), 0.0686940 secs] 301951K->23624K(995776K), 0.0689110 secs] [Times: user=0.36 sys=0.05, real=0.07 secs] 32.440: [GC 32.441: [ParNew: 292606K->14985K(309056K), 0.0206040 secs] 298376K->20755K(995776K), 0.0208320 secs] [Times: user=0.20 sys=0.00, real=0.02 secs] 42.626: [GC 42.626: [ParNew: 289737K->15467K(309056K), 0.0138100 secs] 295507K->21237K(995776K), 0.0139830 secs] [Times: user=0.10 sys=0.00, real=0.01 secs] 56.633: [GC 56.633: [ParNew: 290219K->17334K(309056K), 0.0170930 secs] 295989K->23105K(995776K), 0.0173130 secs] [Times: user=0.12 sys=0.01, real=0.02 secs] Can anyone help me to understand these messgaes related to GC ? -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/Problem-in-Spark-Streaming-tp7310p7384.html Sent from the Apache Spark User List mailing list archive at Nabble.com.
