There are some known data loss bugs related to indexing and region splits in 4.14.0, that are fixed in later 4.14 patch releases, though those events are generally quite noisy with WARNINGs in the logs.
However, AFAICT 4.14.1 and later dropped HBase 1.2 and CDH5 support, so I don't think you'll find an Apache release that has those fixes and works with your HBase version. regards Istvan On Sat, Oct 10, 2020 at 8:13 PM Jins George <jins.geo...@aeris.net> wrote: > Hello Community, > > > > We are facing a wired issue in production with Phoenix write operations. > We use phoenix query server to UPSERT/DELETE records and all the calls > returns success.
