Tim Armstrong commented on IMPALA-9367: --------------------------------------- This may not actually be possible, because the Java side of Impala shares a ticket cache with the C++ side, but it doesn't look like the Java implementation of kerberos supports the same in-memory credential cache. > Allow specifying MEMORY kerberos credential cache > ------------------------------------------------- > > Key: IMPALA-9367 > URL: https://issues.apache.org/jira/browse/IMPALA-9367 > Project: IMPALA > Issue Type: Improvement > Components: Security > Reporter: Tim Armstrong > Assignee: Tim Armstrong > Priority: Major > Labels: kerberos > > Currently --krb5_ccname defaults to "/tmp/krb5cc_impala_internal" and > requires that the argument be an absolute path. > Kudu actually defaults to "MEMORY:kudu" as its credential cache, which may > have some advantages, e.g. it doesn't depend on the filesystem. > It would be reasonable to allow setting the credential cache type to MEMORY. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
