[GitHub] [incubator-doris] caoyang10 opened a new issue #4351: [Bug] ES queries always route at same 3 BE nodes
caoyang10 opened a new issue #4351:
URL: https://github.com/apache/incubator-doris/issues/4351
I create a external ES table and test some queries on ES.Then I find all of the queries route at same 3 BE nodes.
I find the code at fe/fe-core/src/main/java/org/apache/doris/planner/EsScanNode.java
227: candidateBeList.add(backendList.get(beIndex++ % numBe));
numBe is always 3 when number of be is greater than 3. So that candidateBeList always add 3 front of beckendList.
It should be corrected like:
candidateBeList.add(backendList.get(beIndex++ % backendList.size()));
Then FE can balance ES queries between BE nodes.
