apache spark - How to set up dynamic allocation on Cloudera 5 in YARN? -

-

i'm trying run spark dynamic resource allocation on cloudera 5 using yarn.

in spark documentation properties required set on yarn-site.xml missing cloudera configuration interface. though set manually properties in yarn-site.xml , add yarn-shuffle.jar classpath, shuffling service not working.

i got following exception

org.apache.hadoop.yarn.exceptions.invalidauxserviceexception: auxservice:spark_shuffle not exist

this worked me:

if have cloudera deployed, go cloudera manager (port 7180) have cdh 5.6.0

go yarn (mr2 included) -> configuration -> nodemanager default group -> advanced

in textbox associated "nodemanager advanced configuration snippet (safety valve) yarn-site.xml" paste following:

<property>     <name>yarn.nodemanager.aux-services</name>     <value>spark_shuffle,mapreduce_shuffle</value>   </property> <property>     <name>yarn.nodemanager.aux-services.spark_shuffle.class</name>     <value>org.apache.spark.network.yarn.yarnshuffleservice</value> </property>

click on save changes. actions -> deploy client configuration actions -> restart

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
