Lev Bronshtein commented on PHOENIX-4533: ----------------------------------------- HttpParamImpersonationQueryServerIT is now passing as well, patch attached > Phoenix Query Server should not use SPNEGO principal to proxy user requests > --------------------------------------------------------------------------- > > Key: PHOENIX-4533 > URL: https://issues.apache.org/jira/browse/PHOENIX-4533 > Project: Phoenix > Issue Type: Improvement > Reporter: Lev Bronshtein > Assignee: Lev Bronshtein > Priority: Minor > Attachments: PHOENIX-4533.1.patch, PHOENIX-4533.2.patch, > PHOENIX-4533.3.patch > > > Currently the HTTP/ principal is used by various components in the HADOOP > ecosystem to perform SPNEGO authentication. Since there can only be one > HTTP/ per host, even outside of the Hadoop ecosystem, the keytab containing > key material for local HTTP/ principal is shared among a few applications. > With so many applications having access to the HTTP/ credentials, this > increases the chances of an attack on the proxy user capabilities of Hadoop. > This JIRA proposes that two different key tabs can be used to > 1. Authenticate kerberized web requests > 2. Communicate with the phoenix back end -- This message was sent by Atlassian JIRA (v7.6.3#76005)
