recursive way. And currently there's no way to turn this off.\r\n\r\nWhy turn
it off: I want to replace some variables in a simple template. Some of the
replacement values are arbitrary user input.\r\n\r\nAt the moment I escape all
dollar signs in the replacement values with "$$". This is annoying.
Especially as I use one template with variables as a value for another
variable. Here I have to escape twice.\r\n\r\nHere's some example code. At the
moment it prints "Hello world". The commented line is my suggestion
for this feature. If it works, it should print "Hello

threshold to reject items whose weight exceeds the threshold as we go from
mapper to combiner to reducer. The majority part of the algorithm will be very
similar to SimpleRandomSample, except that we do not use Berstein's theory to
accept items and replace probability p = k / n, k is the number of items to
sample, n is the total number of items local in mapper, combiner and

running, check out http://localhost:25020/jvm-threadz, which you will see
referenced offhand in
http://impala.apache.org/docs/build/html/topics/impala_webui.html. That page
has the stack traces the ticket (IMPALA-5392) is talking about. You can see
that several end in ellipses, indicating they are cut off. Fixing that is the
aim of this ticket.\r\n\r\nIn www/jvm-threadz.tmpl, you will see the template
for creating
this page. The section to fix is "{{summary}}". To see where this is
populated, git grep jvm-threadz. There you will see it is referenced in
be/src/util/thread.cc. The references to summary in that file are getting that
information from a TJvmThreadInfo object, so we'll need to trace where the
summary field of that object is populated. That object is referenced in
common/thrift/Frontend.thrift, which is its definition, and in
fe/src/main/java/org/apache/impala/common/JniUtil.java. In that file, you will
see setSummary called with the result of a call to
java.lang.management.ThreadInfo.toString(), which is described
here:\r\n\r\nhttps://docs.oracle.com/javase/8/docs/api/java/lang/management/ThreadInfo.html#toString--\r\n\r\nInvestigate
those docs and find a way to add more stack trace information. Once you think
you have it, you will need to rebuild and restart the
cluster:\r\n\r\n./buildall.sh -notests -noclean -ninja
-start_impala_cluster\r\n\r\nReload the webpage and adm

\r\n\r\nThe ticket in question is
https://issues.apache.org/jira/browse/IMPALA-5314, "Rename single letter
tables in FE tests". First, get your development environment set up. Then,
since this is a ticket about frontend ("FE") tests, you'll want to
check that your frontend tests are passing. Following
https://cwiki.apache.org/confluence/display/IMPALA/How+to+load+and+run+Impala+tests:\r\n\r\n(pushd
fe && mvn -fae test)\r\n\r\nThis particular ticket proposes to change
single-letter table names to names less likely to collide with a developer's
existing environment. Let's check to see what these look like. Run
bin/impala-shell.sh and:\r\n\r\n[localhost:21000] > create table t (id
int);\r\nQuery: create ta
ble t (id int)\r\nFetched 0 row(s) in 0.04s\r\n[localhost:21000] > create
table p (id int);\r\nQuery: create table p (id int)\r\nFetched 0 row(s) in
0.03s\r\n\r\n\r\nNow run your frontend tests again. At the moment I am writing
this, that causes 15 failures. Doing a very simple search-and-replace (using
git ls-files and sed), I replaced " table p " and " table t
" with " table JohnJacobJingleheimerSchmidt ", which reduced the
number of failures to 11. This likely means that this simple method will help
four tests could be made resilient to developer-created single-letter table
names.\r\n\r\nNext, drop the tables t and p that you created above via
bin/impala-shell.sh. Run the frontend tests again and carefully inspect the
output. This will help you fix any tests broken by the simple
search-and-replace.\r\n\r\nOnce all the tests are passing again, you can send
your patch for review following
https://cwiki.apache.org/confluence/display/IMPALA/Contributi
ng+to+Impala. Your patch doesn't have to fix the entirety of the ticket to be
sent for review. It is probably good to get one patch under your belt before
sending any large patches. One this patch is committed and in Impala, you can
come back to this ticket and continue to fix single table names in future
patches.\r\n\r\nOne place you'll want to look for those is in
testdata/workloads/functional-planner/queries/PlannerTest/*.test. These files
are test data for use in fe/src/test/java/org/apache/impala/planner/*Test.java.
For those, a more complex search-and-replace pattern will remove some issues,
but it won't fix everything.\r\n\r\nHave fun!",

but requires a high interest in learning how to describe Earth Observation data
(for example from remote sensing image). The contributor will need to become
familiar with some international standards like ISO 19115. For example if the
contributor get an image partially covered by clouds, he would need to find in
which ISO 19115 field we can declare the percentage of clouds. Once the
contributor became familiar with the ISO 19115 international standard, the task
would be to:\r\n\r\n* Review the mapping done in Apache SIS between some
formats (NetCDF, LANDSAT, ISO 19139) and ISO 19115:2014. This is also a way to
get familiar with those metadata conventions.\r\n\r\n* Get the NetCDF Earth
Observation (EO) Metadata Conventions published by the European Space Agency
(ESA) and improves Apache Spatial Information System (SIS) so it can understand
at least part of those conventions.\r\n\r\nThis task may fit well to
peoples who are interested in environmental sciences.",
