commit 702e5bed72886f09ba3ac66ac5c114526fd43414 Author: liyuntao <[email protected]> AuthorDate: Mon Feb 17 18:41:06 2020 +0800 explicit statement env 'BOOKIE_MEM' and 'BOOKIE_GC' for values-mini.yaml (#6340) Fixes #6338 ### Motivation This commit started while I was using helm in my local minikube, noticed that there's a mismatch between `values-mini.yaml` and `values.yaml` files. At first I thought it was a copy/paste error. So I created #6338; Then I looked into the details how these env-vars[ were used](https://github.com/apache/pulsar/blob/28875d5abc4cd13a3e9cc4f59524d2566d9f9f05/conf/bkenv.sh#L36), found out its ok to use `PULSAR_MEM` as an alternative. But it introduce problems: 1. Since `BOOKIE_GC` was not defined , the default [BOOKIE_EXTRA_OPTS](https://github.com/apache/pulsar/blob/28875d5abc4cd13a3e9cc4f59524d2566d9f9f05/conf/bkenv.sh#L39) will finally use default value of `BOOKIE_GC`, thus would cover same the JVM parameters defined prior in `PULSAR_MEM`. 2. May cause problems when bootstrap scripts changed in later dev, better to make it explicitly. So I create this pr to solve above problems(hidden trouble). ### Modifications As mentioned above, I've made such modifications below: 1. make `BOOKIE_MEM` and `BOOKIE_GC` explicit in `values-mini.yaml` file. Keep up with the format in`values.yaml` file. 2. remove all print-gc-logs related args. Considering the resource constraints of minikube environment. The removed part's content is `-XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCApplicationStoppedTime -XX:+PrintHeapAtGC -verbosegc -XX:G1LogLevel=finest` 3. leave `PULSAR_PREFIX_dbStorage_rocksDB_blockCacheSize` empty as usual, as [conf/standalone.conf#L576](https://github.com/apache/pulsar/blob/df152109415f2b10dd83e8afe50d9db7ab7cbad5/conf/standalone.conf#L576) says it would to use 10% of the direct memory size by default. --- deployment/kubernetes/helm/pulsar/values-mini.yaml | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/deployment/kubernetes/helm/pulsar/values-mini.yaml b/deployment/kubernetes/helm/pulsar/values-mini.yaml index 207b4cd..fa23cc9 100644 --- a/deployment/kubernetes/helm/pulsar/values-mini.yaml +++ b/deployment/kubernetes/helm/pulsar/values-mini.yaml @@ -146,7 +146,8 @@ bookkeeper: ## templates/bookkeeper-configmap.yaml ## configData: - PULSAR_MEM: "\"-Xms128m -Xmx256m -XX:MaxDirectMemorySize=128m -Dio.netty.leakDetectionLevel=disabled -Dio.netty.recycler.linkCapacity=1024 -XX:+UseG1GC -XX:MaxGCPauseMillis=10 -XX:+ParallelRefProcEnabled -XX:+UnlockExperimentalVMOptions -XX:+AggressiveOpts -XX:+DoEscapeAnalysis -XX:ParallelGCThreads=32 -XX:ConcGCThreads=32 -XX:G1NewSizePercent=50 -XX:+DisableExplicitGC -XX:-ResizePLAB -XX:+ExitOnOutOfMemoryError -XX:+PerfDisableSharedMem -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX [...] + BOOKIE_MEM: "\"-Xms128m -Xmx256m -XX:MaxDirectMemorySize=128m -Dio.netty.leakDetectionLevel=disabled -Dio.netty.recycler.linkCapacity=1024 -XX:+ParallelRefProcEnabled -XX:+UnlockExperimentalVMOptions -XX:+AggressiveOpts -XX:+DoEscapeAnalysis -XX:ParallelGCThreads=32 -XX:ConcGCThreads=32 -XX:G1NewSizePercent=50 -XX:+DisableExplicitGC -XX:-ResizePLAB -XX:+ExitOnOutOfMemoryError -XX:+PerfDisableSharedMem\"" + BOOKIE_GC: "\"-XX:+UseG1GC -XX:MaxGCPauseMillis=10\"" PULSAR_PREFIX_dbStorage_writeCacheMaxSizeMb: "32" PULSAR_PREFIX_dbStorage_readAheadCacheMaxSizeMb: "32" PULSAR_PREFIX_journalMaxSizeMB: "2048"
