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 =

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.
