java - Unable to connect to Phoenix using JDBC -


i have hadoop cluster set hbase , phoenix , i'm trying connect phoenix using jdbc, sort of unable successful connection.

i want use jdbc connect using python 3.x simple test purposes set connection using java in eclipse.

i using 3rd party library (phoenixdb) python, started getting timeouts using library (as database grows). after changed variables in settings of hbase-site.xml, avoid timeout, reason didn't solve problems using 3rd party library.

so tried move on jdbc , java project instead - @ least testing.

i have following java code:

public class phoenixtest {      static final string jdbc_driver = "org.apache.phoenix.jdbc.phoenixdriver";     static final string db_url1 = "jdbc:phoenix:https://xx.xx.xx.xx:8765/";     static final string db_url2 = "jdbc:phoenix:xx.xx.xx.xx:8765/";      public static void main(string[] args) {         connection conn = null;         statement st = null;          try {             class.forname("org.apache.phoenix.jdbc.phoenixdriver");              system.out.println("connecting database..");              conn = drivermanager.getconnection(db_url);             st = conn.createstatement();              st.close();             conn.close();          } catch (sqlexception se) {             se.printstacktrace();         } catch (exception e) {             e.printstacktrace();         } {             try {                 if (st != null)                     st.close();             } catch (sqlexception se2) {             }             try {                 if (conn != null)                     conn.close();             } catch (sqlexception se) {                 se.printstacktrace();             }         }     }     system.out.println("finished!"); }

and piece of code , client.jar seems settings changed being recognized queries taking 10 minutes (600.000 ms - changed default 60.000 ms) before connection closed unlike use of phoenixdb library in connection closed after using default timeout (60.000 ms).

when use db_url2 following error:

java.sql.sqlexception: org.apache.hadoop.hbase.client.retriesexhaustedexception: failed after attempts=36, exceptions: thu apr 06 11:13:35 cest 2017, null, java.net.sockettimeoutexception: calltimeout=60000, callduration=80236: row 'system:catalog,,' on table 'hbase:meta' @ region=hbase:meta,,1.1588230740, hostname=hadoopslave,16020,1490706604328, seqnum=0

which doesn't match timeout time of 600.000 ms. when using db_url1 seems use client.jar , timeout time have set inside of .jar (hbase-default.xml), have set 300.000 ms, test 1 used. using db_url1 following error:

java.sql.sqlexception: org.apache.hadoop.hbase.client.retriesexhaustedexception: can't locations

which assume means can't find ip.

however never successful connection hoping have suggestions going wrong?

thanks @paulbastide managed connection using following link:

jdbc:phoenix:thin:url=http://<query_server>:<port>;serializa‌​tion=protobuf

i used thin-client found phoenix distribution.

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
