[jira] [Updated] (HADOOP-18855) VectorIO API tuning/stabilization

     [ https://issues.apache.org/jira/browse/HADOOP-18855?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steve Loughran updated HADOOP-18855:
------------------------------------
    Description: 
Changes needed to get the Vector IO code stable.

Specifically
* consistent behaviour across implementations
* broader testing
* resilience

+Ideally, abfs support. (s3a prefetching needs this too; see HADOOP-19144)

This work will be shaped by the experience of merging support into libraries and identifying issues/improvement opportunities

h2. the patches which MUST be cherrypicked from this to any branch with vector IO support are (currently)

* HADOOP-19098
* HADOOP-19204
