Subject [jira] [Updated] (HDFS-9227) Check block checksums for integrity
Date Tue, 15 Dec 2015 22:37:46 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9227?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

James Clampffer updated HDFS-9227:
----------------------------------
    Attachment: HDFS-9227.HDFS-8707.000.patch

Initial checksum patch, still need to figure out how to do a CI test.

CRC implementations are copies of what the java client uses with a few small modifications.
 Needed to get rid of the hardware accelerated implementations in order to do static linkage.
 Those rely on a loader hook to patch a function pointer to the correct hardware implementation
depending on system architecture.
