[GitHub] [hadoop] fapifta opened a new pull request #2965: HADOOP-17675 LdapGroupsMapping$LdapSslSocketFactory ClassNotFoundException
fapifta opened a new pull request #2965:
URL: https://github.com/apache/hadoop/pull/2965
As stated in this article:
https://www.infoworld.com/article/2077344/find-a-way-out-of-the-classloader-maze.html
A native thread has its context classloader set to null by default.
If the context classloader which is used internally by JNDI to load a class is
null, then the bootstrap classloader is used, according to the apidoc here:
https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#forName-java.lang.String-boolean-java.lang.ClassLoader-
JNDI uses this form with the context classloader as can be seen here:
https://github.com/openjdk/jdk11u/blob/master/src/java.naming/share/classes/com/sun/jndi/ldap/VersionHelper.java#L107
or here:
https://github.com/openjdk/jdk8u/blob/master/jdk/src/share/classes/com/sun/jndi/ldap/VersionHelper12.java#L72
In Impala this call happens from a Thread created in native space, so in that
case, the System/Application classloader loads LdapSslSocketFactory fine in
LdapGroupsMapping.getDirContext() while creating the environment, but then
InitialDirContext constructor gets to instantiation the LdapSslSocketFactory
inside JNDI with the help of the linked VersionHelper impelmentations,
and fails to load the class with the bootstrap classloader as context
classloader is null.
In order to solve this problem, we can safely use the classloader of the
LdapGroupsMapping class, as it had to load the LdapSslSocketFactory class
before.
