Akira AJISAKA commented on HADOOP-12766:
----------------------------------------
I'm thinking we can change the default value to "true" in core-default.xml
because the default value "false" in core-default.xml is no-op before
HADOOP-12735.
In addition, I'm thinking we can move the following source code into
CommonConfigurationKeys.java for testing (See HADOOP-12738 for the detail).
{code:title=NativeIO.java}
static final String WORKAROUND_NON_THREADSAFE_CALLS_KEY =
"hadoop.workaround.non.threadsafe.getpwuid";
static final boolean WORKAROUND_NON_THREADSAFE_CALLS_DEFAULT = true;
{code}
> The default value of "hadoop.workaround.non.threadsafe.getpwuid" is different
> between core-default.xml and NativeIO.java
