Eric Yang updated HADOOP-15922: ------------------------------- Hadoop Flags: Incompatible change,Reviewed > DelegationTokenAuthenticationFilter get wrong doAsUser since it does not > decode URL > ----------------------------------------------------------------------------------- > > Key: HADOOP-15922 > URL: https://issues.apache.org/jira/browse/HADOOP-15922 > Project: Hadoop Common > Issue Type: Bug > Components: common, kms > Reporter: He Xiaoqiao > Assignee: He Xiaoqiao > Priority: Major > Fix For: 3.3.0, 3.1.2, 3.2.1 > > Attachments: HADOOP-15922.001.patch, HADOOP-15922.002.patch, > HADOOP-15922.003.patch, HADOOP-15922.004.patch, HADOOP-15922.005.patch > > > DelegationTokenAuthenticationFilter get wrong doAsUser when proxy user from > client is complete kerberos name (e.g., user/hostn...@realm.com, actually it > is acceptable), because DelegationTokenAuthenticationFilter does not decode > DOAS parameter in URL which is encoded by {{URLEncoder}} at client. > e.g. KMS as example: > a. KMSClientProvider creates connection to KMS Server using > DelegationTokenAuthenticatedURL#openConnection. > b. If KMSClientProvider is a doAsUser, KMSClientProvider will put {{doas}} > with url encoded user as one parameter of http request. > {code:java} > // proxyuser > if (doAs != null) { > extraParams.put(DO_AS, URLEncoder.encode(doAs, "UTF-8")); > } > {code} > c. when KMS server receives the request, it does not decode the proxy user. > As result, KMS Server will get the wrong proxy user if this proxy user is > complete Kerberos Name or it includes some special character. Some other > authentication and authorization exception will throws next to it. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
