[jira] [Commented] (ACCUMULO-3662) Verify correct looking JAVA_HOME in build_native_library.sh

["Christopher Tubbs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-3662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14365580#comment-14365580 ] 

Christopher Tubbs commented on ACCUMULO-3662:
---------------------------------------------

To be clear, the Makefile does the extracting from the environment. We could modify the Makefile to print a reasonable error message instead of build_native_library.sh.
Under what circumstances have you seen this, though? When a JDK was not installed?

> JAVA_HOME needs to be set to a valid JDK to run {{build_native_library.sh}} successfully. Either it's extracted from the environment or it's set in accumulo-env.sh.
> Either way, when it isn't set (or set incorrectly), we should catch this, print a warning and exit the script to prevent the deluge 'JNI_EXPORT' related error messages.
