o	I moved the static parts of the client and server distributions to “src/assembly/resources” and added an assembly that builds the client and server inside the target directory (You need to update the documentation on this)
o	The sever is now available at server/target/iotdb-server-0.9.0-SNAPSHOT
o	The client is now available at client/target/iotdb-client-0.9.0-SNAPSHOT
o	I updated the integration tests to work with these new locations
-	I updated the distribution module (binary-distribution) to simply include and unpack the client and server assemblies, which greatly simplifies the assembly itself.
-	In the integration-tests you use a process builder to get the current working directory … you can access this in the “user.dir” System property.
-	There was a large mixture of artifacts with different versions in the classpath.
o	I set all versions to the same using a big dependencyManagement block in the master pom
o	I removed the version of every external dependency and moved it into the main dependencyManagement block in the root pom (except dependencies only used in the examples, for these I added a dependencyManagement block in the example pom). This way you instantly identify external dependencies.
o	I added an enforcer rule to fail the build if two differing versions of one artifact are being used in the build (This should eliminate this problem from re-occuring)
o	I replaced the usage of “${project.version}” with the real version (There is no need to manually update these versions and this way when looking at the pom you instantly know the version … keep in mind if an artifact is deployed to maven central, the user doesn’t have the code and therefore he always has to scroll up to the top in order to see which version is used)
-	There were some imports related to Jdk 11 no longer providing some APIs, I moved those imports to a maven profile, which is activated based on the JDK version
-	HDFSInputTest created a file in “spark/test/” … if the test failed, the rat plugin would complain the next time it’s run.

I checked the build with all tests on Oracle-Java 8, Open-JDK 11, Oracle-JDK 12.

* rename modules

* add time cost statstic

* BufferWriteProcessor: remove fileName (because insertFilePath is enough)

* TsFileResource: remove relativePath; using autoRead for automatically initialize startTimeMap and endTimeMap

* IMemTable, AbstractMemTable: add returned value of delete()
* TsRecord: change dataPoints from List to Array. And in many other classes, if Array is enough, then replace List<> by Array.

* For insertion, add a new method write(long time, Object value) to replace write(long time, String value), because the latter has to call a switch-case and something like Integer.valueOf(value).

* move recovery function from TsFileSequenceReader to its subclass

* add append option in TsFile writer and add a subclass of TsFileSequenceReader for supporting auto repair

* fix stream unclosed when exception occurs when creating TsFileReader

* reject writes when the memory is dangerous

* faster memtable.getSortedTimeValuePairList

* reduce memory cost when sorting data in memory

* fix equals() method in InsertPlan

* make TsFileWriter as AutoClosable; make TsFileReadWriteTest more concise

* make stop tsfileProcess more safe

* add a log appender: put info, ware, error log into one file; disable the log_info file

1. modify asf header for each file; 2. enable apache-rat-plugin; 3. add more exclusive files on apache-rat-plugin and license-maven-plugin, i.e., *.json, *.md, and *.csv

* format Almost for obeying Google Java Style.

* fix the problem of checkstyle

* fix license-format template file location

* add apache header check plugin

* add fotmat plugin

* move format code to verify phase

* change to compile phase

* change to verify phase

* remove special char in .travis

* remove useless code

* add apach header and format codes

* Update MavenWrapperDownloader.java
