# This is a readme for hadoop-version-dfs-dir.tgz and hadoop-dfs-dir.txt.
|
|

|
# See HADOOP-1629 for more info if needed.
|
|
# These two files are used by unit test TestDFSUpgradeFromImage.java

|
|
# hadoop-dfs-dir.txt :
|
|
# ---------------------
|
|
# Along with this description this file contains the expected files and
|
|
# checksums or the files in the upgraded DFS.
|
|
#
|
|
# The original DFS directory was created with various types of files and with
|
|
# some recoverable errors (i.e. corrupt or missing .crc files).
|
|
#
|
|
# A similar set of files exist in two different DFS directories.
|
|
# For e.g. "top-dir-1Mb-512" contains files created with dfs.blocksize of 1Mb
|
|
# and io.bytes.per.checksum of 512.
|
|
#
|
|
# To generate checksum info for new files :
|
|
# ---------------------------------------
|
|
# Uncomment the last coment (starts with "printChecksums") and run the
|
|
# test again. When the test sees this line, it prints the checksum
|
|
# information that should replace the checksum information in
|
|
# this file. When run in this mode, the test will fail with a descriptive IOException.
|
|
#
|
|
# Next, extract the checksum info from the test log like this:
|
|
# sed -n 's/.*CRC info for reference file : //p' test-log.txt >> this_file
|
|
# This will append a new list of files and checksums to this file. Be sure to remove the existing checksum info.
|
|
#
|
|
# For your reference, the format of the checksum info below is "filename whitespace*\twhitespace* checksum\n"
|
|
#
|
|
# Uncomment the following line to produce checksum info for a new DFS image.
|
|
#printChecksums
