hadoop - Can't start master and slave, strange thing named "bogon" in the log -


i downloaded new pre-build spark hadoop 2.2 file. following this document, want launch master on single machine. after untar file, enter sbin , start-master, face strange problem, here log:

spark command: /library/java/javavirtualmachines/jdk1.7.0_55.jdk/contents/home/bin/java -cp :/opt/spark-0.9.0-incubating-bin-hadoop2/conf:/opt/spark-0.9.0-incubating-bin-hadoop2/assembly/target/scala-2.10/spark-assembly_2.10-0.9.0-incubating-hadoop2.2.0.jar -dspark.akka.loglifecycleevents=true -djava.library.path= -xms512m -xmx512m org.apache.spark.deploy.master.master --ip bogon --port 7077 --webui-port 8080 ========================================  log4j:warn no appenders found logger (akka.event.slf4j.slf4jlogger). log4j:warn please initialize log4j system properly. log4j:warn see http://logging.apache.org/log4j/1.2/faq.html#noconfig more info. exception in thread "main" org.jboss.netty.channel.channelexception: failed bind to: bogon/125.211.213.133:7077     @ org.jboss.netty.bootstrap.serverbootstrap.bind(serverbootstrap.java:272)     @ akka.remote.transport.netty.nettytransport$$anonfun$listen$1.apply(nettytransport.scala:391)     @ akka.remote.transport.netty.nettytransport$$anonfun$listen$1.apply(nettytransport.scala:388)     @ scala.util.success$$anonfun$map$1.apply(try.scala:206)

what's bogon? , ip 125.211.213.133(not ip) comes from? what's problem here?

"bogon" comes command line provided. forgot replace parameter --ip local ip of host.

when using sbin/start-master.sh, if not ip provided, reported hostname of machine used: start-master.sh

if [ "$spark_master_ip" = "" ];   spark_master_ip=`hostname` fi

if reported hostname not right, can provide spark ip setting env variable.

spark_master_ip=172.17.0.1 start-master.sh

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
