Bug fixesedit

Aggregations
  • Fix early termination of aggregators that run with breadth-first mode #44963 (issue: #44909)

  • Fix a bug where mappings are dropped from rollover requests. #45411 (issue: #45399)
  • Sparse role queries can throw an NPE #45053
Machine Learning
  • Check dest index is empty when starting data frame analytics #45094
  • Catch any error thrown while closing data frame analytics process #44958
  • Only trap the case where more rows are supplied to outlier detection than expected. Previously, if rows were excluded from the transform after supplying the row count in the configuration, we detected the inconsistency and failed outlier detection. However, this situation legitimately happens in cases where the field values are non-numeric or array valued. #569
Mapping
  • Make sure to validate the type before attempting to merge a new mapping. #45157 (issues: #29316, #43012)

  • Fix URI path being lost in case of hosted ES scenario #44776 (issue: #44721)
Search
  • Prevent Leaking Search Tasks on Exceptions in FetchSearchPhase and DfsQueryPhase #45500
  • Fix an NPE when requesting inner hits and _source is disabled. #44836 (issue: #43517)
