scala - loading csv file to HBase through Spark -


this simple " how " question:: can bring data spark environment through com.databricks.spark.csv. know how create hbase table through spark, , write data hbase tables manually. possible load text/csv/jason files directly hbase through spark? cannot see talking it. so, checking. if possible, please guide me website explains scala code in detail done.

thank you,

there multiple ways can that.

  1. spark hbase connector:

https://github.com/hortonworks-spark/shc

you can see lot of examples on link.

  1. also can use spark core load data hbase using hbaseconfiguration.

code example:

val filerdd = sc.textfile(args(0), 2)   val transformedrdd = filerdd.map { line => converttokeyvaluepairs(line) }    val conf = hbaseconfiguration.create()   conf.set(tableoutputformat.output_table, "tablename")   conf.set("hbase.zookeeper.quorum", "localhost:2181")   conf.set("hbase.master", "localhost:60000")   conf.set("fs.default.name", "hdfs://localhost:8020")   conf.set("hbase.rootdir", "/hbase")    val jobconf = new configuration(conf)   jobconf.set("mapreduce.job.output.key.class", classof[text].getname)   jobconf.set("mapreduce.job.output.value.class", classof[longwritable].getname)   jobconf.set("mapreduce.outputformat.class", classof[tableoutputformat[text]].getname)    transformedrdd.saveasnewapihadoopdataset(jobconf)    def converttokeyvaluepairs(line: string): (immutablebyteswritable, put) = {      val cfdatabytes = bytes.tobytes("cf")     val rowkey = bytes.tobytes(line.split("\\|")(1))     val put = new put(rowkey)      put.add(cfdatabytes, bytes.tobytes("paymentdate"), bytes.tobytes(line.split("|")(0)))     put.add(cfdatabytes, bytes.tobytes("paymentnumber"), bytes.tobytes(line.split("|")(1)))     put.add(cfdatabytes, bytes.tobytes("vendorname"), bytes.tobytes(line.split("|")(2)))     put.add(cfdatabytes, bytes.tobytes("category"), bytes.tobytes(line.split("|")(3)))     put.add(cfdatabytes, bytes.tobytes("amount"), bytes.tobytes(line.split("|")(4)))     return (new immutablebyteswritable(rowkey), put)   }
  1. also can use one

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
