Subject [jira] [Commented] (HADOOP-10224) JavaKeyStoreProvider has to protect against corrupting underlying store
Date Fri, 01 Aug 2014 17:23:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14082553#comment-14082553

Alejandro Abdelnur commented on HADOOP-10224:

In the constructor, the {{throw new IOException("Keystore cannot be loaded !!");}} should
be more descriptive of the problem, why is the exception is being thrown, that CURRENT &
_NEW exists, and it should not be the case, only one should be there.

In the constructor, when loading the CURRENT and having an error other than bad password we
should log that CURRENT was corrupted and we loaded OLD. We should rename CURRENT to _BAD_$DATE,
and report that as well for an admin to delete it.

When loading _NEW and corrupt, we should report that in the exception message clearly. Also,
shouldn’t we be renaming _NEW to CURRENT here?

"// Check if _NEW exists (incase flush had finished writing but not", typo "in case"

"KeyStore intialized anew sucessfully" 2 typos, "KeyStore initialized anew successfully"

{{isBadorWrongPassword()}} method, always use {}s for IF blocks.

{{loadFromPath()}}, you don’t want to rename until you know you can load the keystore, i
would do the rename outside of here.

{{flush()}}, when renaming files verify rename is successful (boolean return value) and fail
if not.

> Java keystores get corrupted at times. A key management operation that writes the store
to disk could cause a corruption and all protected data would then be unaccessible.
