Relocating shards in elasticsearch -


step 1) creating node named "node1"

step 2) creating new index in node1 named "application" , in index type "testing"

step 3)index created 5 shards. no replicas

step 4)now insert 5 doc in index. splitted among 5 shards

step 5)now initiate new node called "node2" in node1's cluster.

step 6) per understanding shared shards between nodes. 2 shards moved new node

question 1)now request document @ node1 present in relocated shards(shards moved node1 node2)

question 2) search return requested document or not

question 3) how 2 nodes communicate each other

question 4) can read , write in node2 ? if yes can search same data written node2 node1..

thanks in advance..!

all answers yes :)

the nodes communicate each other through transport port, default 9300 port (or first 1 free in (9300-9400] range. use custom binary protocol communicate, based on serialization of objects (not standard java serialization in of cases though).

any node in cluster cluster-aware , knows shards , on, share called cluster state. can send requests (read , write) node , rerouted interesting nodes , executed depending on type of request.

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
