Hi, I have a Spark streaming(Spark 2.1.0) app where I see these logs in executor. Does this point to some memory leak?
17/05/16 15:11:13 WARN Executor: Managed memory leak detected; size = 67108864 bytes, TID = 7752 17/05/16 15:11:13 WARN Executor: Managed memory leak detected; size = 67108864 bytes, TID = 7740 17/05/16 15:11:13 WARN Executor: Managed memory leak detected; size = 67108864 bytes, TID = 7764 17/05/16 15:11:13 WARN Executor: Managed memory leak detected; size = 67108864 bytes, TID = 7728 17/05/16 15:12:02 WARN Executor: 1 block locks were not released by TID = 7783: [rdd_1_15] 17/05/16 15:12:02 WARN Executor: 1 block locks were not released by TID = 7807: [rdd_1_39] I notice that "Managed memory leak" logs are not seen when I use G1GC.
