Apache spark: setting spark.eventLog.enabled and spark.eventLog.dir at submit or Spark start -

-

i set spark.eventlog.enabled , spark.eventlog.dir @ spark-submit or start-all level -- not require enabled in scala/java/python code. have tried various things no success:

setting spark-defualts.conf as

spark.eventlog.enabled           true spark.eventlog.dir               hdfs://namenode:8021/directory

or

spark.eventlog.enabled           true spark.eventlog.dir               file:///some/where

running spark-submit as:

spark-submit --conf "spark.eventlog.enabled=true" --conf "spark.eventlog.dir=file:///tmp/test" --master spark://server:7077 examples/src/main/python/pi.py

starting spark environment variables:

spark_daemon_java_opts="-dspark.eventlog.enabled=true -dspark.history.fs.logdirectory=$sparkhistorydir -dspark.history.provider=org.apache.spark.deploy.history.fshistoryprovider -dspark.history.fs.cleaner.enabled=true -dspark.history.fs.cleaner.interval=2d"

and overkill:

spark_history_opts="-dspark.eventlog.enabled=true -dspark.history.fs.logdirectory=$sparkhistorydir -dspark.history.provider=org.apache.spark.deploy.history.fshistoryprovider -dspark.history.fs.cleaner.enabled=true -dspark.history.fs.cleaner.interval=2d"

where , how must these things set history on arbitrary jobs?

i solved problem, yet strangely had tried before... same, seems stable solution:

create directory in hdfs logging, /eventlogging

hdfs dfs -mkdir /eventlogging

then spark-shell or spark-submit (or whatever) can run following options: 

--conf spark.eventlog.enabled=true --conf spark.eventlog.dir=hdfs://<hdfsnamenodeaddress>:8020/eventlogging

such as:

spark-shell --conf spark.eventlog.enabled=true --conf spark.eventlog.dir=hdfs://<hdfsnamenodeaddress>:8020/eventlogging

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
