Andrew Sherman commented on HIVE-18791:
---------------------------------------
The test TestJdbcWithMiniHS2.testHttpHeaderSize() is testing that HS2 can be
reconfigured
to use different maximum sizes of http headers when Thrift uses http as its
transport.
In this mode the http header contains a user name and password encoded using
http basic
encoding. The original test varies the length of the user name to test (1) that
that a
too large header fails with 413 Payload Too Large, and (2) that increasing the
maximum
sizes of http headers allows the large header to work. In HS2 when the
connection is made
a Session is created (note that in this configuration the user name and
password are not
verified). The local scratch directory for the session uses the username as
part of its
path. When this name is more than 255 chars (on most modern file systems) then
the
directory creation will fail. HIVE-18625 made this failure newly throw an
exception, which
caused a regression in testHttpHeaderSize() when the session was created with a
long user
name. Fix this by having the test vary the password rather then the user name.
The test
is functionally identical but does not hit the directory creation exception.
