On SonarQube 7.7 Developer Editon C++ build wrapper version 6.3 (build-wrapper-linux-x86-64):
I get every now and then (after max. 10 runs) the following exception when running the scanner:
java.lang.IllegalStateException: Unrecoverable indexation failures: 1 errors among 1 requests at org.sonar.server.es.IndexingListener$1.onFinish(IndexingListener.java:39)…
After that every consecutive scanner run fails.
I saw that also others have reported this issue here, but my understanding is that they got rid of it after deleting the ES data once, like this:
rm -rf /opt/sonarqube/data/es*
It also works for me temporarily, but the problem is coming back after a couple of runs as described above.
Any hint what to check in ElasticSearch config or elsewhere?
